Acceptable Values

Msg. Number

1 to 4 digits (1 to 9999)

Slave Address

1 to 3 ASCII digits (1 to 127)
0 or null = use slave address selected as a message attribute
127 = all slaves

DL40 Address

1 to 3 digits (0 to 127)
127 = all DL40s on RS-485 link

Note: If 0 or no slave address is input, the slave address selected as a
message attribute is used.

Note: The DL40 address is optional if triggering a message via the keyboard.
If no DL40 address is sent, the message will be triggered on the DL40 that
the keyboard is plugged into. If a DL40 address is specified, the message will
run only if the address is 127 or if it matches the address of the DL40 that the
keyboard is plugged into. If no DL40 address is sent when using the RS-485
link, the message trigger will be ignored.

If no DL40 address is sent, the second backslash ( \ ) is optional.

If no Slave Address or DL40 Address is sent, both backslashes are optional.

Note: If the Remote I/O Port is inactive or faulted, the Last State switch
(number 8 on SW2) must be ON to trigger messages from the keyboard or
via the RS-485 Port.
