7.1.18.2 Monitoring Control Input/Output Signals (B5 and 25 Driver Units)
l State of Input and Output signals of connector CN2 can be monitored by the IO command.
l This function is useful for checking the wiring.
l Input format
IO0/RP: Monitors general I/O state.
IO2/RP: Monitors I/O state related to positioning with Programmable Indexer.
IO3/RP: Monitors I/O state related to positioning in general.
/RP default: Monitors in one shot.
/RP attached: Monitors in real time.
l Readout format: Bit map representing Input/Output in 1 line.
(See Table 7-11.)
à The readout is the current Input/Output state.
à The line of “I/O change state” on the display in Figure 7-22 holds the first readout state
on each Input/Output to indicate that this part was changed at least once before.
à Press the BS
key to terminate the real time monitoring (IO*/RP).
à Press the R
key to reset the monitored state in the Input/Output changing state.
