Dear Mahesh N, may I ask you whatinformation you are looking for exactly? If you are planning to write your own modbus function blocks have a look at this site: http://www.modbus.org/ You will find all Information about the modbus protocol in order to develop your own driver. Good luck! |

Dear Mahesh N, Q: How to switch to the next slave device? A: Just set the SLAVEaddress atthe MAMAREQ block accordingly. Q: How many devices we can connect? A: Max. 254slaves (Slave numbers 1 to 254) Q: Can we minimize data update rate? A: Yes you can. - Try to arrange your data in the slave so that you use as less as muchnumber of MBMAREQ calls. - Another option is to reduce the cycle time of the MBMA340 (you need to try that out). If you like my blocks, rate them! Best Regards. |

Hello Mahesh N, no, as Kaulquappealready mentioned the SI uses different standard communication blocks. I canmodify the blocksfor the SI module as well, but I need such module for testing it. I can offerthe Modbus Master RTU software driver for the CP341 as well if anybody is interested. That driver is working withoutthe need of the hardware dongle in the CP. Best Regards. |
