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
and how to confirm or change them.

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 ... 2000ms, and it must be specified as
an increment of 20ms.

For our example, we will change the timeout value to 240ms.

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 change the setting to

HOLD

.
