To communicate through fiber optics with the E-Flo
DC Control Module, reference the appropriate
hardware as shown in manual 332356. That
manual indicates various options for connecting
fiber optic cables from the control module to the
non-hazardous area. The following table lists
Modbus registers available to a PC or PLC located in
the non-hazardous area.
