Hello Tim, Well, CMD_A and CMD_B is used in the OB35 for the FC30. The FC30 is using at first CMD_A and pass this command to s_CMD3. After 100ms the OB35 is called once again. The FC30 is using now the CMD_B and pass this command to s_CMD3. After 100ms the OB35 is called once again. The FC30 is using now the CMD_A again and pass this command to s_CMD3, and so on … I created a little sketch where you can see how this mechanism works. It is only necessary to write 2033 to CMD_B only one-time. The service mode is only necessary if you want to send the DR3 from the PLC to the WP241 module OR if you are executing adjustment commands, like “Start initial zero calibration” or “Start span calibration with test weight”. Please note: In the Step7 example project the OB30 is used instead the OB35. Best regards Siwarexi AttachmentCommand_Trigger_WP241_en.pdf (264 Downloads) |
