Hi John,

I believe it is set by the timeout value that you pass to modbusInterposeConfig in your startup script.

All,

I am using Modbus R3-2, ASYN R4-40

I have a Binary Input record read from a block of coils configured via

drvAsynIPPortConfigure("s1eps", "192.168.184.17:502",0,0,1)

and

drvModbusAsynConfigure("MI_3_IN","s1eps",255,2,505,4,0,500,"Koyo")

My question is:  what sets the timeout value for an EPICS TIMEOUT_ALARM in this case?

Thanks,
