■Assignment of pin number and signal
The assignment range of the general-purpose input-and-output signal is fixed by the setup of the station
number.
Although the combined use with the parallel I/O interface (2D-TZ368/2D-TZ378) of another option is also
possible, please use the setup of the station number by the different number separately.
Table 3-31: Assignment of pin number and signal
The connector pin number of the parallel I/O unit of the station number 0 and signal number assignment are
shown in Table 3-32 and Table 3-33. If it is set as other station number, please interpret and utilize.
