Confirming the Peer Cop Summary Information
Overview
Once you have defined the link and accessed a node, the Peer Cop summary
information values assume default settings. This section describes those settings.
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.
For our example, we will use the default setting.
On Error
The default On Error setting is
CLEAR
.
The
On Error
setting specifies how the Peer-Copped device will treat the last values
received before a timeout, once Modbus Plus communications have been restored.
One of two settings may be used–
CLEAR
or
HOLD
.
CLEAR
sets all the previously
received values to 0, and
HOLD
retains the previous values.
For our example, we will use the default setting.
