Program No. Selection Method
<EtherCAT and EtherNet/IP I/O Signals to be Used>
Program No. selection input bit 0 to 3 (Input signal 1 - bit 0 to 3 / input data byte 0 - bit 0 to 3)
Program setting input second digit / Program No. selection input bit 4 (Input signal 1 - bit 4 /
input data byte 0 - bit 4)
Program setting input first digit / Program No. selection input bit 5 (Input signal 1 - bit 5 / input
data byte 0 - bit 5)
Start input (Input signal 1 - bit 8 / input data byte 1 - bit 0)
When PRM36 is set to 1, 2, or 3
After program number setting is made, selected programs are executed one by one from the
first one after the start signal is supplied next time.
If the same program number as that of the already set program is set again, the program is
executed in the same way from the top.
One of the following methods can be selected with the setting of PRM36 (I/O program number
selection method switching).
<4 bit BCD double selection (PRM36=1: default setting)>
Bit 0 to 3 (Input signal 1 - bit 0 to 3 / input data byte 0 - bit 0 to 3) for program No. selection input
enables to set the second (10 digit) and first digit (units digit) data in this order.
The number data is specified by 4 bit BCD (binary coded decimal).
Consequently, the selectable numbers of programs are 0 to 99 (100).
* Enter a bit signal (0: 0000 to 9: 1001) by BCD (binary coded decimal).
If a bit signal outside the above range is entered, an unexpected program No. is selected and malfunction may
be caused.
