Chris, I am not sure if I follow exactly what you are doing, but it sounds like you want to connect the IN parameter of a COUT block from OFL_1 of a PLB block and then have the COUT block drive CO_7 directly in a different FBM. You need to set the COUT IOMOPT =1 and then enter the FBM's ECB name (not the PLB block) into IOM_ID and the physical output CO number into PNT_NO. COUT.IN = DCI_5.OFL_1 COUT.IOMOPT = 1 COUT.IOM_ID = <ecb_name> * See COUT description in B0193AX COUT.PNT_NO = 7 However, I do not know if it is allowable to directly connect to an output of an FBM that is running ladder logic. I gave this a quick try on our system. I created a COUT block as described above and tried connecting to an unused output in a FBM10/13 combo running ladder logic. I got the same W51- Invalid Hardware/software type error. An FBM9 with ladder logic will have an ECB8 where as one without will have an ECB5. This may be your problem. Perhaps one of the IPS (IOM) guys can verify if this is correct. Tom Badura Plastics Engineering Company tbadura@xxxxxxxxxx -----Original Message----- All, Working on Ver.8.3 Windoz with CP271. 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.
