Command mapping setting example
■Definitions of messages
• Define the transactions of base host command sending messages (S2F41).
• Because the number of parameters is variable, the number of parameters in the list is defined by a variable length list.
• Because the maximum number of parameters is three, three parameter lists are defined.
■Definitions of command mapping by parameters of key items
• Use the mapping setting function to specify the remote commands <RCMD> of the host command sending messages
(S2F41) for the keywords of message mapping. Because receiving data of primary messages and return data of secondary
messages are both subject to mapping, specify "Use the same offset for secondary messages".
• Specify the item value of <RCMD> to the parameter, and then specify the sending request trigger relays and reception
notification trigger relays of messages and offsets for the command registers of message items.
■Setting example for host command sending message (S2F41) definitions
The following section shows a setting example for host command sending messages (S2F41) and an example of command
mapping by remote command.
