5.2 Message Send Function
If a request is sent assuming that the 263IF-01 is a client for explicit message transmission or a response is sent as a
server, the message send function (MSG-SND) is used.
If a response is not returned from the remote station within 10 seconds after sending a message, the 263IF-01 detects a
timeout and the MSG-SND function ends abnormally.
5.2.1 Outline Specifications
∗ The I/O designations are as follows:
B-VAL: I/O is specified as bit data.
I-REG: I/O is specified as integer data. Specify the number of an integer register.
Constants (immediate data) can also be specified for inputs.
Address input: The address of the specified register (any integer register) is passed to the function.
