The loader operator’s panel is used to jog the loader and perform teaching.
For the loader operator’s panel, the I/O signals described below are stored
on the loader control board.
DI = 8 points (+24 V contact signal input)
DO = 6 points (LED drive sink output)
DO = 4 points (common voltage drive source output)
DI = 1 point (+24 V contact signal input, emergency stop input signal)
These I/O signals are used for loader operator’s panel switch input and
driving LED indicators.
The common voltage drive source output is provided to interface with
switches and LEDs connected in matrix format. The use of a matrix
format enables the number of input and output points to be increased to
32 and 24, respectively. In this case, the system software supports control
of the common voltage drive source output for matrix scanning, so that
no PMC program is required. Bit 1 of parameter No. 7902 is used to
specify whether to use a matrix connection.
