Other Default Settings in the Peer Cop Dialog Box
Overview This section describes the default settings for Health Timeout and Last Value.
Diagram The first time you access the Peer Cop dialog box, the following screen appears:
Health Timeout The default timeout is 500 ms.
Timeout is the maximum interval that Modbus Plus on a Peer-Copped device will
remain healthy without communication activity. If this interval is exceeded, the
device will clear its network health bit and will no longer try to communicate via
Modbus Plus.
The timeout interval must be in the range 20...2000 ms, and it must be specified as
an increment of 20 ms.
Last Value The default Last Value setting is Clear on timeout. This setting specifies how a peer-
copped device will treat the last values received before a timeout, once Modbus Plus
communications have been restored.
