Can I use both ports A and B simultaneously on the B885-002 module?



No. Ports A and B on the B885-002 module cannot be used simultaneously. Only one port can be running at any given time. The B885-002 module has a slide switch for either RUN or PROGRAM. If the slide switch is set to PROGRAM, then one port has to be used for the programming device. If the slide switch is set to RUN, then both ports can be used for field devices.
