I am not sure what the real question is, but if the FBM is configured for PLB, then the PLB.CO_X is the only thing that can write to the FBM output. You can connect the PLB.CO_X to other block boolean inputs like the .IN parameter of a COUT block, but the COUT block can not be configured with the letterbug of a FBM that is configured as PLB. The .COUT parameter of a COUT block that is configured with IOMOPT of 0 can be connected to the PLB.IFL_X parameter and then passed through PLB logic to the CO_X. As s a further note, CIN (and similar blocks) can be connected directly to inputs of a FBM that is configured with PLB by entering the FBM letterbug and FBM point in the CIN block.

I have FBM9/14 expansion set up for ladder logic. Is there any way to access the COUT param through a COUT, MTR, GDEV, or other block with out having to use up IFL's in the ladder? I have logic in a different ladder with DCI_5.OFL_1 mapped to DIO_3.IFL_29. CO_7 is the output I need. The ladder is IFL_29 CO_7 69 ---| |------------------------------------------------------------( )--- MPC-07- MPC-07- 115 INP 115 OUT I would like to set the DCI_5.OFL_1 to the .IN on a COUT block but I am unable to set the COUT block IOM_id. I am getting a W51- Invalid Hardware/software type. According to what I have read, it looked like the COUT was the only way to make this work but I cannot get the .COUT of the COUT block mapped to a CO_X. Thanks in advance for your help. I am looking forward to the responses.
