WP321 with ET200SP CPU1512C problem

Hello LReniers,

To your questions:

1) I can not read any value in DR34 ASCII DISPLAY (this value is used in the siwarex HMI example project).

Are you reading the DR34 to the PLC with the command “2034”?

2) When a follow quickstart menu in the siwarex HMI example project, the automatic calibration does not work .

What happens if you execute the command “82” (= Automatic calibration) into the DB321?

Which flag goes to TRUE: “bo_CMD_FinishedOK” or “bo_CMD_FinishedError”?

Best regards

Hello LReniers,

Well, with the command “710” (or 701, 705, 714, 715, 871, 875) you can only select the value (gross-weight, net-weight, …), which you want to see into the Siwatool-software and into the DB321 in the PLC.

But anyway, you have to read the DR34 to the PLC with the command “2034”, see also the Table 10-1 into the chapter 10:

2000 + X:

Reading of a data record, X corresponds to the data record number.

Example: Data record 3 transmitted by SIWAREX module to the SIMATIC CPU → 2000 + 3 = command code 2003

Hello LReniers,

I downloaded the current example project from the internet:

The command code “2034” is used at the address DB321.DBW448.

Together with the OB30, this command "2034" is used for s_CMD3.

Best regards
