Hi, I am new to GE, just got an additional plant to cover with three GE PLC's on a network, running Proficy Machine Edition. THe first two plc's turn on a flashing red light on the building on a new alarm. I need to make the third plc also flash the light on a new alarm in it.
There already is logic for a new alarm to sound a horn in the control room. I parallelled a new coil in the same rung as the horn logic. Edit: the rung text doesn't come through as typed. QSP4 is branched under the horn
.QSP1
--------[newalm]---------------------(horn)
..........................l
..........................l......... QSP4
..........................l----------(light)
The horn was added previously and the output for it is QSP1(spare relay 1). I am using QSP4 (spare relay 4), also provided with the original install.
My issue is that when I put in the 'coil' for QSP4, the output has an M inside it. The horn output has bold lettering QSP1, and no M inside the coil. The properties for both coils look the same. The logic knew that QSP4 was for 'spare relay 4. The rung does work, when I have a new alarm, relay 4 is energized, I wired the N.O. contacts, and the flashing light on the building flashes until the alarm is acknowledged. Just wondering about that M inside the coil. Thanks in advance.
