PLC Setup Section 7-1
Response Monitoring Time
Function Block Communications Instructions
DeviceNet Communications Instruction Response Monitoring Time
Note The number of resends and response monitoring time must be set by the user
in the FB communications instructions settings in the PLC Setup, particularly
when using function blocks from the OMRON FB Library to execute FINS
messages or DeviceNet explicit messages communications. The values set in
this PLC Setup for OMRON FB Library will be automatically stored in the
related Auxiliary Area words A580 to A582 and used by the function blocks
from the OMRON FB Library.
