Troubleshooting a PeerWay
Three screens are useful in diagnosing PeerWay problems. See the
Service manual, SV:10--1, for definitions of the screen fields.
Peerway N ode Screen [PN] xx
This screen shows details for the named node (xx). Observe Qual A and
Qual B, Noecho, Badecho, DupNode, AB Swap, and Coupler.
PeerWay Overview Screen [PO]
A dot indicates no errors, a number shows the number of errors, and **
indicates more than 99 errors. A vertical line of errors indicates a
transmission problem, a horizontal line indicates a reception problem.
The A and B columns at the right side show each node’s opinion of
PeerWay A and B quality. Zero is perfect; 100 is a warning; and 500 shows
very poor communication performance.
A node can be disconnected from PeerWay A by entering “A” at the prompt
on the right. “B” disconnects the node from PeerWay B. ”AB” disconnects
both PeerWays.
The Actual margin should be between 495 and 505. A lower margin
indicates a PeerWay B problem, a higher one indicates a PeerWay A
problem.
Plant Status Screen [PS]
This screen shows the device at each node. Backlighting indicates
ownership of the device by this console.
