Moxa ioLogik E2210 [129/263] Heartbeat interval

ioLogik E2200 Series Active OPC Server

6-11

Heartbeat Interval

Tags are event-driven and updated only when the status of an I/O channel changes, so when the status

remains unchanged, there an update will not be sent to Active OPC Server. To ensure that the ioLogik is

connected and alive, Heartbeat Interval can be used to determine the connection status between the ioLogik

and Active OPC Server. If the heartbeat interval is set and the network between the ioLogik and Active OPC

Server is down, Active OPC Server will detect the stop of the heartbeat and the Quality column will show BAD

to indicate the loss of the connection. The default interval is set to 0 seconds, which disables the heartbeat. The

maximum allowed interval is 65,535 seconds.

Read/Write Privilege

The R/W column shows whether a tag is read only, or provides both read and write access. The input channels

can be read, but cannot be written to, whereas the output channels can be both read and written to. Note that

if an output channel has been used by the Click&Go logic, the tags for that channel are read-only.
