This section explains the allocation and applications of the Q64TC I/O signals.
(1) The Q64TC uses 16 input points and 16 output points to transfer signals to/from
the programmable controller CPU.
(2) Table 3.4 lists the I/O signals used by the Q64TC.
Inputs (X) mean the signals from the Q64TC to the programmable controller CPU
and outputs (Y) the signals from the programmable controller CPU to the Q64TC.
(3) The I/O signals (X, Y) indicated in this manual assume that the module is loaded
on the I/O slot 0 of the main base unit.
If the Q64TC is mounted on other than the I/O slot 0, change the I/O signals for
those of the slot where the module is mounted.
(4) When the Q64TCTTBW or Q64TCRTBW is used, the device numbers of the I/O
signals increase by 16 points depending on how many free points the left-hand
side slots have.
Hence, as I/O signals are given as indicated below in this manual, read them
according to the module used.
Example) When a signal is given as Yn1
When the Q64TCTT or Q64TCRT is used: Y1
When the Q64TCTTBW or Q64TCRTBW is used: Y11
