Hello! I faced with problem on writing value to Up/Down counter using VM. Details: - I created a small diagram to use this counter as light switch (this is only way i found to control light power using hardware wall-mount impulse button and software modbus switch on HMI). - Linked "Count" parameter to VD10 via "VM mapping" - Started simulation - Saw that VD10 == current count on counter (linking is OK) - But cannot write value to counter in simulation (without any errors) OS Win10 x64 and Ubuntu 16.04. SW version 8.1.1 and 8.2. Questions: 1. What is cause of the problem? 2. Maybe it's possible to solve my task more gracefully? Who can suggest? Thanks in advance!

In simulation mode, it is not possible to write to the counter reading via a data table. But in online mode it is possible. AttachmentChanging counter value via Data Table.wmv (307 Downloads) |

I do not understand this circuit anyway. That's why I can not offer any improvement. |

I needed a Pulse relay, but with remote state control from the Network. |

The LOGO! Software already has a ready pulse relay.
