I've been reading and writing to the modbus in brains with not problem, but now I want to set a modbus output if the e-stop is enabled.  For instance, if e-stop is enabled, I want to do SetModbusOutput(0, 0).  How would I do that in a brain?  I tried... ESTOP->NOP->MOD:0 and also ESTOP->INVERT->MOD:0.  Those didn't work.

Thanks

Did you come up with a solution to this?  Having a similar problem.
