When using a PLC CPU in the direct mode
Note that when the I/O control mode of the PLC CPU is the direct mode, and if the 1st GOT is connected to the main or
extension base unit with a 5m extension cable (GT15-AC50B, GT15-A1SC50NB), the input X of the empty I/O slot cannot
be used.
No restrictions apply when the I/O control mode is the refresh mode.
