View the PLC Variables Status	To view the Status of the Variables in the PLC, once you are Online with the PLC, from the Main Menu of the SIMATIC Manager Software, click on the PLC (1) selection and select Monitor/Modify Variables (2) from the drop-down menu as shown below. The Variables Monitoring window shown below will open.  From this window, you can enter the Variables and Monitor their states.
Data Block Addressing	Data Block Addressing syntax differs some between what is seen in the SIMATIC Software and in C-more.  To view the Data Block, double click on the specific Data Block you wish to view in the main SIMATIC Manager window.  When a specific Data Block is selected, a window like the one shown below will open.
	From the figure shown above: The image above shows DB1. Inside DB1, there are Four Variables: MOTOR_RPM is addressed at byte0 and is a 16 bit Integer. SETPOINT_RPM is addressed at byte2 and is also a 16bit Integer. START is addressed at byte 4, bit 0 and is a Boolean. STOP is addressed at byte 4, bit 1 and is a BOOLEAN. These Four Variables would be Addressed as follows in C-more: MOTOR_RPM = Memory Type:  DB.DBW  Address:  1.0 SETPOINT_RPM = Memory Type:  DB.DBW  Address: 1.2 START = Memory Type:  DB.DBX  Address:  1.4   Bit:  0 STOP = Memory Type:  DB.DBX  Address:  1.4  Bit:  1

Pengukuran Vibrasi pada Motor atau Pompa

Untuk apa sih mengukur getaran/vibrasi? ini sama seperti kita mengukur tingkat kesehatan manusia, begitu juga kita harus tahu tingkat kesehatan sebuah mesin / motor listrik, salah satu nya ya dengan mengukur dan memonitor vibrasi nya.

Mesin-mesin apa yang harus dimonitor vibrasinya?
secara umum, mesin-mesin yang harus diperhatikan adalah berdasarkan tingkat kepentingan sebuah mesin tersebut antara lain :

a. Mesin yang cukup mahal, besar, dan susah diperbaiki jika terjadi kerusakan
b. Mesin yang memberikan dampak yang besar terhadap produksi sebuah pembangkit (plant)
c. Mesin yang diketahui sering kali mengalami kerusakan
d. Mesin yang sedang diukur kehandalannya
e. Mesin yang memberikan dampak keselamatan terhadap manusia maupun peralatan lain (safety)

Bagaimana instrument pengukuran bekerja?

Sebelum mengukur vibrasi, kita perlu tau sensor apa yang digunakan untuk mengukurnya. Kebanyakan sih yang dipakai adalah sensor accelerometer, jadi dia memproduksi sinyal kecil yang sebanding dengan akselerasi dari peralatan yang bergetar tersebut. Apa sih akselerasi pada komponen yang bergetar? maksudnya seberapa cepat perubahan velocity yang terjadi. apa sih velocity??? mbulet yaa….

Bagaimana mengukur nya?

Pertama, bagaimana meletakkan accelerometer nya? ingat, jika mau mengukur vibrasi di bearing maka jangan letakkan alat ukut di body… contoh seperti dibawah

a. Letakkan sedekat mungkin pada bearing

ini untuk menghindari distorsi signal dan kesalahan dalam pembacaan.

b. Pastikan alat ukurnya terpasang dengan baik

sama, efeknya akan menyebabkan kesalahan dalam pembacaan sinyal oleh alat ukurnya .

c. Pastikan orientasi pengukuran tepat

Jika akan mendeteksi parallel missalignment, maka biasanya alat ukur diletakkan pada posisi radial dari bearing. Sedangkan untuk mengukur angular missalignment, alat ukur diletakkan dalam posisi sumbu axial.
Sinyal yang diproduksi oleh alat ukur akan bergantung juga dari letak dan arah, karena getaran akan bervariasi di setiap letak dan arahnya.

d. Lakukan pengukuran di tempat yang sama.

Dalam melakukan perawatan, predictive ataupun preventive,  maka akan sangat baik jika pengukuran rutin dilakukan pada tempat yang sama..

e. Jaga keselamatan mu dan juga alatmu

In the M580 CPU, why does the system word %SW51 (RTC Hour) show a different value?

In the M580 CPU, why does the system word %SW51 (RTC Hour) show a different value?
How do I extract the value of the current local time hour from an M580 PLC's Runtime Clock (RTC) in a program?

Product Line
Modicon M580

Enviroment
EcoStruxure Control Expert
Unity Pro

Cause
There is a new behaviour of %SW51 in M580 platform compared to the previous M340 generation of PLC. The local time Hour is not represented in %SW51 in the M580.

Resolution
The local time can be read using the RRTC_DT function.

The RRTC_DT function returns the date and time in DateTime Type format.

This value can then be converted to an Array of 4 INTs (in BCD Format) containing:
DateAndTime_ARRAY[1] = 16#SS00  (Seconds)
DateAndTime_ARRAY[2] = 16#HHMM (Hour and Minute)
DateAndTime_ARRAY[3] = 16#MMDD (Month and Day)
DateAndTime_ARRAY[4] = 16#YYYY (Year)

These 4 INTs are structured in the same way as %SW50 to %SW53 in the M340.

Furthermore, to extract the Local time hour using the RRTC_DT function, see the screenshot below as an example:


The value from the DT_TO_ARINT array of INT variables is originally in BCD format and must be converted from BCD to INT. Then the left-most two digits represents the local time hour, which can be extracted by dividing the BCD value by 100 (with no remainder using the DIV function).

Nema Rating

NEMA is a rating system for equipment that might be exposed to liquids, rain, ice, corrosion and contaminates such as dust.

If unsure of the enclosure rating that is required of your project, please refer to the design chart below. The chart will assist in specifying which enclosure rating is appropriate for the environment and application needed.

For in depth information on the different Nema ratings we offer, please continue reading to the list below.

Type 1: General purpose enclosures constructed for indoor use. Protects against dust, light, and indirect splashing but is not dust-tight. Primarily prevents incidental contact with the enclosure equipment. We adhere to NEMA standards to provide you a quality enclosure for most basic applications.

Type 3R: Intended for outdoor use. Provides a degree of protection against falling rain and ice formation. Constructed (with knockouts on the sides and bottom) to prevent beating rain from interfering with the successful operation of the apparatus or result in wetting of live parts and wiring within the enclosure under specified conditions. Please be aware that these are not rain-tight, which means exposure to beating rain could result in water entering a Type 3R enclosure under certain conditions; nor are they water-tight, which means moisture could enter a Type 3R enclosure when subjected to a stream of water under certain conditions. This style of enclosure does not have a gasketed sealing surface. Nema Enclosures manufactures NEMA 3R enclosures for housing power distribution, lighting contractors, switch gear, and other electrical components that need to be protected in an outdoor environment. Our adherence to UL 508A standards will give you a quality weatherproof enclosure resistant to rain, ice, and snow

Type 4: Weather tight (weatherproof) enclosures. Constructed for either indoor or outdoor use to provide a degree of protection against falling dirt, rain, sleet, snow, windblown dust, splashing water, and hose-directed water. Will be undamaged by the external formation of ice on the enclosure. NEMA 4X is used when protection from the worst environments is required. Our NEMA 4 enclosures come in powder coated carbon steel and are available in a variety of types, such as wall-mounted, free-standing and JIC. Nema Enclosures strictly adheres to the exacting NEMA standards in order to provide you a quality electrical enclosure at competitive price.

Type 4X: Same as Type 4 except constructed from corrosion-resistant material. Corrosion-resistant as defined by industry standards is: Constructed to provide a degree of protection against exposure to corrosive agents such as salt spray. Nema Enclosures produces these enclosures in 5052-H32 aluminum, 304/304L stainless steel, or 316/316L stainless steel and they are available in a number of styles for your demanding applications.

Stainless steel is the strongest of the corrosion resistant materials. It exhibits many of the same resistances attributed to fiberglass materials as well as resistance to highly polar solvents such as acetone and MEK.

316 grade stainless steel is the strongest of the corrosion resistant materials that provide improved resistance to salt, some acids, and high temperature. 316 grade is a strongly recommended choice for marine environments which are within 5 miles of salt water or otherwise subject to salt spray. Note that 316 grade resistance to sulfates and chlorine is less than that provided by 304 grade.

Cautionary aesthetic note: Stainless steel of any type is not “stain-free”, and while it offers a high degree of performance, under certain environmental conditions it remains susceptible to rust deposits on the surface. These deposits are often created by contamination resulting from rain or marine environments. Periodic cleaning of the surfaces of stainless steel enclosures with a neutral solution is recommended to avoid “tea staining” Regular washing with clean, fresh water or even rain water has a significant effect on reducing the incidence of tea staining.

Type 12: Constructed (without knockouts) for indoor use to provide a degree of protection to personnel against access to hazardous parts. Provides a degree of protection of the equipment inside the enclosure against ingress of solid foreign objects (falling dirt and circulating dust, lint, fibers, and fyings). Also provides a degree of protection with respect to harmful effects on the equipment due to the ingress of water (dripping and light splashing). Gasketed doors seal the enclosure’s contents from airborne contaminants and non-pressurized water and oil. Nema Enclosures produce NEMA 12 enclosures which are intended mainly for indoor industrial, manufacturing, and machining applications. We produce a number of enclosure types in aluminum, carbon steel and stainless steel delivered quickly at competitive prices.
