Indirect specification of the start input/output number of the CPU module can also be performed by using the
CPU module index register.
Page 446 Access to index the network No. and start input/output number
■Device code and device number
Specify the following devices. (Page 67 Devices)
• CPU buffer memory access device (G)
• CPU buffer memory access device (HG)
For the values of device codes, refer to the following section.
Page 70 Device code list
Using the index register of CPU module, the access target device number can be specified indirectly.
