Using the I/O on Slave (Bussed VXMs)
Most of the inputs and outputs on a Slave VXM (in a Master/ Slave bussed configuration)
are available through the Master. To access the user I/O on the second VXM (Slave) from
the Master use the standard “Ux” commands +100. The Master will subtract 100 from
the “Ux” command and send the result to the Slave.
The following are valid commands for I/O addressing on a Slave:
U100 Wait for a "low" on user input 1
U101 Wait for a low on user input 1, holding user output 1 high while waiting
U104 User output 1 "low" (reset state)
U105 User output 1 high
U102 Enable Jog mode while waiting for an input
U103 Disable Jog mode while waiting for an input
U107 Start of Continuous Index with 10 µsec pulse on output 2
U113 Wait for a front panel button to jump to a program or continue: "Motor 1 Jog -"
button to jump to program #1, "Motor 1 Jog +" button
to jump to program #2, "Run" button to proceed in current program.
U114 User output 2 low (reset state)
U115 User output 2 high
U116 Optional User output 3 low (reset state)
U117 Optional User output 3 high
U118 Optional User output 4 low (reset state)
U119 Optional User output 4 high
U123 Wait for a front panel button to jump to a program and come back, or continue:
"Motor 1 Jog -" button to jump and return to program #1, “Motor 1 Jog +" button
to jump and return to program #2, "Run" button to proceed in current program
U130 Wait for a low to high transition on user input 1
U131 Wait for a low to high transition on user input 1, holding user output 1 high while
waiting
U132 Wait for "Motor 1 Jog -" button to be pressed on front panel with debouncing
U133 Wait for "Motor 1 Jog +" button to be pressed on front panel with debouncing
U150 Wait for a low and high on user input 1 with debouncing for a mechanical push-
button switch
U151 Wait for a low and high on user input 1 with debouncing for a mechanical push-
button switch, holding user output 1 high while waiting
U190 Wait for a low to high on the Run button or connection I/O,4 with debouncing for
a mechanical push-button switch
