I am trying to configure my software to work as a Slave in a modbus system. I am using the FB81 as said in the manual "ss200s_e.pdf" I found in the support web site. The problem is that when I download the software in a physic CPU like 315-2 DP it works wonderfully but when I download it in my WinLC "PC CPU" the FB81 returns an error code 19 that following the manual means: Error during access to the SIMATIC I/Os. Check if the required I/Os exist and are error-free. The error only occuers when the master system sends a modbus telegram to the Slave system. It seens my I/Os configured in the DB900 (Conversion_DB) are not valid, but how could this work in a physic CPU? Well, the software is Attached in this post so if anyone could take a look and help me, I would be glad. Thanks. AttachmentModbusSlave.zip (258 Downloads) |
