Hello Shazin, 1- "Line monitoring capability"!! I'm sure don't mean thisone. I guess you mean wire break/short circuit diagnostics, isn't it?! OK the above diagnostics depend on modules not the CPU. The modules in your avatar support these functions. However, you can still find some standard modules supporting such diagnostics. The point is that you need something that can survive in a temp. more than 60 C. So, you need something that isSIPLUS. Please, check the SIPLUS modules either inSIPLUS S7-300tree orSIPLUS ET200M tree(Maybe you need to logout to go in A&D mall). Check for diagnostic/alarms marked yes. I personally make a test HW configuration and open the module properties to check its diagnostic capabilities to make sure. 2- For CPUs, I'm not sureS7-300 CPUs can reach the 70C. (You better search by yourself). For S7-400, there areCPUsthat can withstand the 70C. If I were you, I would have checked theS7-1500as well. You may also needConversion tool (Siemens standard order number to Siemens SIPLUS extreme order number). 3- Redundant Modbus. For redundant Modbus, please checkthis. Maybe you should contact someone from IT industry or start athread hereto ask about Modbus redundancy in S7-300 or S7-1500. Best regards, H-H |

Hello Shazin, Sorry for the delay. False information. The analog input module and the digital output modules support wire break detection. It's true that the common/famous/mostly used 24 Fail Safe digital input module doesn't detect wire break for digital input signals. However,the Namur onedetects wire break signals if you use proximity sensors or end of line resistors (just take care that there'sa new part number). Cost effective?! I don't know. It requires some calculations and I hope you will be lucky to find the below modules in SIPLUS portfolio. For digital inputs, check321-7BH01. For digital outputs, check322-8BH10. Best regards, H-H

Hello Shazin, You don't need any additional packages to configure these modules. I'm sure the6ES7331-7KF02-0AB0detects wire break in 4-20mA signals. Maybe there are some other modules that can do the same job. I would have asked myself first, Is there aHumanwho can withstand 60C before you think of aHumanMachineInterface for a 60C environment?! Anyhow, if you check theHMI catalog ST80,you will find some SIPLUS basic panels that can operate in 60C. I don't think you have a chance with comfort or PC panels. Best regards, H-H

Hello H-H,
Thank you so much for the information
Thank you so much for the information
Practically not necessary, but the specifications demands so. And i found this Thankfull to you for the usefull informations and prompt reply. Also one last thing if you dont mind, can we use the above mentioned analog module for a three wire instrument(i forgot to mention this information in my previous posts)or do we need seperate module for such instruments? |
