Open Issues and Problems

ID Description

CR75101

Cannot perform simultaneous loads from PLC to two different PCs running VersaPro.

Details: While running with VersaPro on two PCs connected to both serial ports of the PLC,

the following error occurred while trying to perform simultaneous loads on one of the PCs:

Lost communications with com server.

Resolution: The problem is that one connection exceeds its SNP_T2 time while waiting for

the other load to finish. This time is configurable in VersaPro and has a default of 3 seconds.

If this type of operation is required, you should increase the SNP_T2 time until both

operations are successful. To set this parameter, go to the Tools menu and choose

Communications Setup. In the Communications Configuration Utility, choose the Ports tab,

and click the Advanced button.)

CR75600

Write of Flash during Store causes invalid service request.

Details: Using VersaPro to Store Logic and Stored Values from PC#1 while using VersaPro on

PC#2 to perform Flash Read, Flash Write and Flash Verify operations on a 90-70 CPU. After

the Store completes, all attempts to perform a Flash Write from PC#2 produces the following

error:

“Flash/EEPROM/EZ Programmer write failed. Reason: Invalid input parameter in request”.

Resolution: You should avoid doing flash operations if another programmer is storing to the

PLC. If you do encounter this problem, you will need to power cycle the PLC and re-boot the

PC to return to normal operation.

Problem with Loading a folder having a block named ‘SYSTEM’ in VersaPro 2.0x.

Details: If you try to Load a VersaPro program having a block named ‘SYSTEM’ from PLC to

a folder in VersaPro 2.01 or 2.02, the Load will fail and an error message saying ‘Unable to

create local scope SYSTEM’ is displayed in the information window.

Resolution: VersaPro 2.01 onwards has a restriction on naming a block or variable as

‘SYSTEM’. You should Load the folder from PLC into a VersaPro 1.5 folder, rename the

block and re-store the folder to PLC. Now this folder can be Loaded into VersaPro 2.01, 2.02

or 2.03 as well.

Master Hardware Checksum Not Equal in VersaMax CPUs after changing configurable

memory.

Details: Store the hardware configuration for VersaMax CPU001, CPU002 or CPUE05 after

changing the configurable memory limits (%AI, %AQ or %R) in the Memory Tab to

something other than its default value. Perform a Verify of the Hardware Configuration with

the PLC. The Hardware configuration will be verified and ‘Master HWC Checksum Not

Equal’ message will be displayed.

Please note that the Configurable Memory still works even if the verify reports that the Master

HWC checksum is not equal.

VersaMax Nano/Micro Issues:

ID Description

CR71425

High Speed Counters should be disabled by default for VersaMax Nano/Micro PLCs.

Details: When a new Hardware Configuration is made for the Nano/Micro PLC, all High

Speed counter channel function parameters are set to Counter by default. The channels should

actually be set to Standard by default, since during the PLC Auto-configuration of the High

Speed Counter channels should operate as Standard I/O.

Resolution: If High Speed Counter operation is not desired, you can load the auto-

configuration from the PLC or set the counter channel function to Standard.
