About SLC 500
The SLC 500 series is a series of Allen-Bradley programmable logic controllers that are used for a wide variety of applications. The SLC 500 series features Ladder-Logic with a structured text programming. The units are designed for addressing a broad range of applications that include file handling, sequencer, diagnostics, shift register, and immediate I/O and program control instruction applications. The SLC 500 controllers support built-in RS-232, 422, and 423 communication ports. The unit also comes with the DeviceNet and the ControlNet I/O on the selected processors. The SLC 500 series provides controllers that have powerful and affordable performance. These units are designed and built to provide excellent value.
The Allen-Bradley SLC 500 controllers feature modular processes, power supplies, I/O devices, memory options, and communication interfaces that allow the units to have configurable and expandable systems. The units feature an advanced instruction set that includes indirect addressing and a high level of performance capability for delivering computation instructions. The units are programmed to provide the users with a broad selection of the I/O devices. Therefore, the users can select from over 60 modules that help to control the discrete, analog, and temperature signals. The SLC 500 controllers are designed to deliver power and flexibility with a wide range of communication configurations. The SLC 500 modular hardware style controllers allow for the section of the processor, power supply, and I/O modules. The units also come with optional memory modules that provide a non-volatile memory in a convenient modular form. When using the commercial PROM programmers for programming and erasing the memory module, adapter sockets are required.
SLC 500 troubleshooting
-
Ensure the card is slid into the rack allowing both bottom and top clips to lock into place
-
Check that the entire rack has power
-
Allow a 1-5 min power cycle
-
Check pins on the back side of the card where a connection is made into the rack
-
Take the card out and do a visual inspection of the card outside of the rack, checking that resistors, capacitors, TRIACs and chips all look functional
-
Check to see that power supply is screwed into the rack and properly mounted
Processor Communications
-
Make sure your RS-232 cable is making a good connection with both the computer and processor
-
Check that the proper COMM port and driver is being used in RS-Linx
-
For SLC 5/03 and up apply screwdriver across GND and VBB for 1 min, this will reset COMMS
Read I/O configuration
-
Check to ensure you are reading the correct driver in rs-linx
-
Research error codes
Rack not powering on
-
Check power supply
-
Try inserting power supply into another rack
-
Check voltage going into power supply and ensure correct sumpers are selected if there any
-
Check pins on the back slide of the power supply that plug into the rack
-
Check manual for proper insulation and power requirements for multiple power supplies
-
Add your amperage rating for each device
If the rack is still not powering on, the application you are using could require more amperage than the supply is rated for
Example:
The 1747-L551 draws 1A at 5v DC
The 1746-OV16 requires 0.270 A according to documentation
The 1746-P2 supplies 5A at 5vDC to the backplane
Checking to see if our power supply can handle the load we would use the following formula:
IT=I1+I2+I3
Using this formula, we can see that since 1a + .27a = 1.27a ,
the 1746-P2 would handle this load no problem
If none of these solutions solve the problem, there could be a faulty card killing your whole rack
-
Remove each card one at a time to check if there is a card causing issues in the rack
