Dear All, We are currently using Modbus TCP/IP Library for third party communication in our project with PCS7 V7.1 SP4. We are using “Modbus_TCP_CP_Red300_400” Library for programming. In this library there is a block called "Job List" (FB 912), which is used to generate multiple queries/jobs for the Modbus Client block (MB_REDCL). The default block have maximum 5 Jobs. In my project I required 8 jobs to call via this block. For this I used the procedure given in below manual: Modbus/TCP Add-On Blocks (Entry-ID: 62830463, V1.0, 07/2014), the link for the same is - https://support.industry.siemens.com/cs/document/62830463/add-on-blocks-for-modbus-tcp-communication?dti=0&lc=en-WW With the help of above manual (refer page no. 12), I increased the no of jobs to 8 for the "Job List" Block. But after doing this the "Job List" block doesn't work. To understand the same I have attached the zip file containing "before" and "after" folder. I have questions as below: 1. Why the "Job List" block is not working after increasing the inputs to 8? 2. Is there any way to call 8 jobs using two standard Job List (with 5 Jobs) blocks? Please help if anyone has done this before. AttachmentModbus TCP_IP - Job List Block.zip (494 Downloads) |
