My 3150-MCM is configured to have no Write Data, only Read Data. Occasionally, I am seeing my data overwritten with what appears to be configuration data.

3150-MCM write block count and write block start are both set to 0. The write block start parameter must be set to a value which does not overlap with the read data area. A write start value of 75 will generally take care of this problem. In the sample ladder for the 3150-MCM, re...

When using the sample ladder I get an M0/M1 file reference error in my SLC processor if the MVI46 or 3150 is not in Slot 1.

The M0 and M1 files are slot referenced. The second digit in the address represents the slot number. If the MVI46 or 3150 module is in slot 1 (next to the processor), then the file reference is M0:1.XXXX and M1:1.XXXX If the module is in slot 5, then the file reference would b...

How do I deal with an unsigned integer in an SLC, PLC5, or MicroLogix processor?

Scenario: A device that uses an INT value to represent a range of 0 to 65535, but in the processor the INT tag has a range of -32768 to 32767.Since the A/B processor does not have an unsigned Integer data type, you will need to convert this value to represent the full range. Simp...

My 3150-MCM block IDs are incrementing until I connect the communications cable. Once the cable is connected, the block ID stops incrementing.

Verify the cable matches the diagram on page 50 of the user manual. If pins 7 and 8 are not jumpered, and there is communications on pins 1 or 9, your backplane transfers will fail. The error status data will also show an error code of 255....
