Why Omron WS02-SIMC1-E - V1.9 REV 02-2009 failed to start FinsGateway?
If Omron Software fails to start FinsGateway, it may have been installed incorrectly or the settings are invalid due to a wrong execution environment. Re-install the CX-Programmer and the CX-Server, or FinsGateway.
How to fix Omron WS02-SIMC1-E - V1.9 REV 02-2009 Software CX-Simulator Ladder Engine communications error?
If a communications error occurs with the Omron CX-Simulator Ladder Engine, it may be due to a wrong communications environment. First, try disconnecting and connecting again. If that doesn't work, close all applications except the CX-Simulator. As a last resort, uninstall and then reinstall the CX-Simulator Software.
What to do if Omron Software CX-Simulator Ladder Engine failed to gain the access rights?
If the Omron CX-Simulator Ladder Engine fails to gain access rights, another application program might be writing to the UM. After the application program being writing is completed, try again.
Why Omron WS02-SIMC1-E - V1.9 REV 02-2009 failed to switch the current UM and failed to gain the access rights of CX-Simulator Ladder Engine?
If the Omron CX-Simulator Ladder Engine fails to switch the current UM and fails to gain access rights, another application program might be writing to the UM. After the application program being writing is completed, try again.
How to fix Omron Software Alarms display application failed to start?
If the Omron Alarms display application fails to start, it might be due to a wrong environment for the Alarms display application. The event viewer is not working for Windows NT and the memo pad for Windows95/98. Change the OS settings so as to work.
What to do if The node address of FinsGateway unit is duplicated in Omron WS02-SIMC1-E - V1.9 REV 02-2009?
If the node address of FinsGateway unit is duplicated in Omron Software: 1. Change the FINS node address of the communications path in the [Work CX-Simulator] window. 2. Change the duplicated node address using network communications setting.
How to resolve Omron WS02-SIMC1-E - V1.9 REV 02-2009 Software failed to create a header of FINS response (Fins_sendData)?
If the Omron Software fails to create a header of FINS response (Fins_sendData), it may be due to a wrong destination address of the FINS command. Check the destination of the FINS command sent by the Ladder Engine or application program or settings of the routing table.
What to do if an attempt was made to operate a FINS that was not for CPU Unit in Omron WS02-SIMC1-E - V1.9 REV 02-2009 Software?
If an attempt was made to operate a FINS that was not for CPU Unit in Omron Software, it may be due to a wrong destination address of the FINS command. Set "0" to the FINS unit address for the destination of the application that sent the FINS command.
Why Omron WS02-SIMC1-E - V1.9 REV 02-2009 Software program is running and I cannot set a start point?
If the Omron Software program is running, you cannot set a start point because you tried to set a start point while running the program. A start point can be set only when stopping (Program mode).
