CPP Monitor 2000 User’s Manual
Advanced Comm Setup
The Advanced Comm Setup form can be used to tune and custom-
ize the communication performance of Manager 2000. Typically
you will not need to change these parameters for any reason.
Listed below is a description of each of the parameters on the form:
Status Level: This parameter determines which messages will
appear in the display on the Communication Status form. There are
eight levels of messages:
Level 0:Messaging disabled
Level 1:Adds significant events and errors
Level 2:Adds modem events, writes to unit & file messages
Level 3:Adds packet errors, advanced modem messages,
download messages
Level 4:Adds notification of read from unit
Level 5:Adds packet data
Level 6:Adds notification of input status polling
Level 7:Adds polling packet data
Packet Retries: Information flows back and forth between CPP
Monitor 2000 and your PC in data “packets.” Both automatically
check for packet transmission errors. When a bad packet is detected,
it gets sent again. Packet Retries determines how many times a
packet is sent before a communication error is logged.
Error Threshold: Determines how many consecutive errors will
result in a disconnect.
Retry Time Out: This is the amount of time Manager 2000 will wait
for a response from a CPP Monitor 2000 unit before it decides to
make another request.
Packet Time Out: The amount of time before the PC gives up and
determines that an individual modbus request has timed out.
Decreasing this parameter will not increase performance, but
increasing the parameter may remove occasional errors.
