ID Description

CR75914

Ethernet communications problems after upgrading to LM9070 Release 7.05.

Details: After installing LM9070 Release 7.05, you may find that VersaPro will not connect

with the PLC when using an Ethernet connection.

Resolution: You should re-install VersaPro and this will resolve the problem.

CR76447

Host Driver Timeout when storing Maximum size C program to flash.

Details: When writing a maximum size c block to flash, a host driver timeout error occurs.

This happens when connected serially and also via Ethernet.

Resolution: Since the C program/block is large, the write to flash takes approximately 23s to

complete. This exceeds the VersaPro default Global Request time-out parameter and results in

the time-out failure. This problem will occur for any program (C, LD, or IL) that takes longer

than the VersaPro default Global Request time-out that is 16s.

To correct this problem the following must be adjusted in VersaPro:

1) Open the CCU - Communication Configuration Utility (Go to the Tools menu and select

Communications Setup menu option)

2) Select the Ports Tab.

3) Select the communication port in use (say COM1) and click the Edit button.

3) Click the Advanced button on the Edit Port dialog.

4) Change the Request Timeout to 30000ms (30s).

5) Click the OK button.

6) Select the Global Parameters Tab.

7) Click the Edit button.

8) Change the Request Timeout to 30000ms (30s).

9) Click the OK Button.

10) Click the OK Button on the CCU dialog.

11) VersaPro must now be disconnected and reconnected from the PLC for the new time-out

parameters to take effect.

CR75957

Clear All Produces Temporary Loss of Communications with VersaMax CPUs.

Details: When attempting a clear all or read/write/verify of the EZ Programmer with VersaPro

to a VersaMax CPU via a serial connection, communications can be temporarily lost and the

clear never completed when there are several expansion racks of modules. Occasionally,

communications are lost for a few seconds, then re-established, but the clear never completes.

Resolution: You should increase the request timeout period and the SNP_T5P timeout to

30,000 or greater. This will keep VersaPro from timing out when the PLC is busy with one of

these longer operations.
