Hy, does somebody know where channel 9 is for? I know channel 0-4 are the dipswitches and channel 5-8 are the leds on top of the module. In the fieldpoiunt explorer there is also a channel 9 available. Where can i find its connector, indicator, ...? Where can you use it for?
Channel 9 is used to indicate which power supply is providing power to the network modules, the primary or the secondary. This channel only functions on rev C or later versions of the FP-20XX modules.
