Mapping Specifications Of Eh-Iocd - Hitachi HIDIC EH-150 Applications Manual

11.3 Mapping Specifications of EH-IOCD

If I/O modules are mounted by setting a empty slot on the EH-IOCD, the empty slot is ignored when mapping to
the link area. Only the mounted modules are mapped, for each input/output module.
The following shows an example:
