Hi guys,
I have two Modicon 984 connected via Modbus Plus. The first PLC has a BMOT card attached to it to control a linear slide.
I made some changes to the program off line and downloaded the code after clearing the PLC memory using the "Initialise Logic" command which wipes the memory completely.
I downloaded the code and restarted the PLC controller and my linear slide start acting funny. It's full stroke is 9" and normally homes in one continuous movement. However, it would start homing moving 1" at a time and then stop before moving another inch.
Eventually I disconnected the power to the CPU and when I powered it back up the 2nd time the linear actuator worked properly again.
This isn't the first time that this has occurred. We have 33 of these slides and they go funny the odd time that we download a program.
Has anybody any ideas what I might be doing wrong?
Thanks,
Colm
