For example, host command sending messages (S2F41) have different parameter (CPNAME, CPVAL) numbers and targets
due to the remote command (RCMD), even when the message structure is the same.
If the mapping function is applied to these messages, message sending request trigger relays and reception notification
trigger relays of each parameter of key items and offsets for control registers of message items can be configured in one
transaction definition.
Therefore, the reference destination or storage destination of parameters can be changed by the values of particular key
items.
Example of locations for applying mapping function
• Mapping host command sending messages (S2F41) by remote command
• Mapping the data of discrete variable data sending messages (S6F3) to message data by load port
Usage method
Configure messages for command mapping in the mapping settings, and then configure command parameters.
■Mapping settings
Mapping settings can be configured at the "Command Setting" screen. ( Page 140 Command setting)
Under "Message", select the message to be command mapped from the pull-down list. Under "Key Item", select the item to be
the mapping key from the pull-down list.
When offsets will be applied to secondary messages as well, select the "Use the same offset for secondary messages"
checkbox.
■Parameter settings (mapping settings by parameters of key items)
At the "Parameter Setting" screen, configure offsets message sending request trigger relays, reception notification trigger
relays, and offsets for control registers of message items for each parameter of key items. ( Page 141 Parameter setting)
