⑥
For SUM2,XOR2,MUL2, mask the above SUM check value (1 byte) and get the SUM Check value.
Example> Masking D3 as FF
1 1 0 1 0 0 1 1

Function block
1) User defined function block (SND_MSG)
Function block
Description
Input
REQ: Execute function block at rising edge (0
→
1)
CH: Set communication channel (0 ~ 1)
FL_ID:
Frame list field number to send.
(0 ~ 15)
Output
NDR: When ends without error, this is set to 1 and keeps till the next request for
function block.
ERR: When an error occurs, this is set to 1 and keeps till the next request for
function block.
STATUS: When an error occurs, output error code.
(1) Function
•
When the execution condition is on, the communication starts with protocol at parameter which is designated early.
•
‘CH’ is a communication channel, and ‘FL_ID’ designates a frame list number which is registered in the user defined
communication parameter.
(2) Program example
•
When input condition (%MX000) is on, channel 1 starts communication with protocol at user defined parameter number 3.

= D3
= D3 (AND Masking)
= FF (OR Masking)
= 2C (Exclusive OR Masking)
= FF
