[SOLVED] SUBSCRIBE_2 and PUBLISH_2 issue [message #1791347]

Hello,

Sorry for writing again. The issue is quite strange because I saw at https://www.eclipse.org/4diac/en_help.php that with events it is supposed to work. Instead, using constant values, it stops working. I made the same to show the issue. Maybe I am wrong, or maybe it is buggy? I am using FORTE 1.9

Thank you in advance!

Hi!

The problem is that RD_1 is unconnected. As RDs are of type ANY, you need to typify the output by connecting it to a typed input. The easiest solution would be to connect an INT2INT FB to you RD_1, in order to correctly typify it.

Best regards
Martin

Hello,

Thank you for your support! It works if you have PUBLISH_2 and SUBSCRIBE_2 in FORTE, as shown in the first image below. But if you have PUBLISH_2 in GUI (Figure 2) and SUBSCRIBE_2 in FORTE (Figure 3) it seems not to respond.

Best regards,
Agostino

Hi!

As you trigger both applications via E_RESTART FBs, have you made sure, that the subscriber is ready, before you send via the publisher? From your screenshots I can see, that FORTE did not receive a message.

Best regards,
Martin

From the screenshot below I see that the receiving connection is open and that then something is received. Structure is the same as before.

Thank you for your time!

EDIT: I have tried with a minimal GUI and PUBLISH_1 and SUBSCRIBE_1. When I click a checkbox, the value is sent. Also in that case, if PUBLISH_1 is given a constant value (like BOOL#1), it is not sent. If, instead, you connect IN_BOOL and PUBLISH_1, everything works. But I need a constant value...

Based on your EDIT, it seems to me, that the problem lies with the FBDK. I am not an FBDK expert, but I would assume, that it does not support typification via constants. Is there a BOOL2BOOL FB available in FBDK? If yes, try to connect it on the SD, the same holds for SD_2 but with an INT2INT respectively.

Best regards,
Martin
