Appendix B Task Codes Specifications
Description
When the subcommand H00 is executed using the task code H20 via the COMM, remote or link module, the I/O
assignment of the module will be erased and the communication with the CPU cannot be performed. In such a case,
connect a programming device to the CPU and perform the I/O assignment operation. Note that the WRITE-occupancy
release operation is necessary when connecting a programming device.
2] Initialization of the HI-FLOW area (subcommand H01)
Only the HI-FLOW area is initialized. (EH-150 does not support HI-FLOW.)
3] Initialization of the HI-LADDER area (subcommand H02)
Only the HI-LADDER area is initialized.
4] Zero clear of all user memory areas (subcommand H03)
Writes zero to all areas equivalent to the load capacity of the memory.
When the subcommand H00 or H03 is executed using task code H20, always execute the task code H27, parameter
modification completion, when the write processing is completed with respect to each user-memory area.
