Hi Philip, Thanks for your reply, I realise that I should have been more specific with my question. I appreciate what Modbus is and the availability of the data table from the vendor, unfortunately in this case they don't offer data over ethernet using Add On Instructions, EDS files etc. I am specifically ...

Modbus comms. to a IGD Tocsin 750

Hi, does anybody have experience of reading data over Modbus from an International Gas Detectors Tocsin 750 device? Apparently Modbus is the only comms. option to this particular unit, Cheers, Andy

Hi Eileen, Unfortunately I haven't been offered a solution to date. All of the data available from numerous manuals and tech notes only describe how to change the operating mode of the module, NOT the operating class. If you select an HSCE2 module in RSLogix 500 there are two hardware options, HSCE2 ...

This is exactly where I am at. When you add the module to the IO tree you can redefine the module definition to have 16 Input and 16 Ouput, which subsequently translates as 8 INT in and 8 INT Out in the controller tags. There appears to be nowhere to set the module ID to 3511 The module configuration ...

Hi Ryan, thanks for the info, this is one that I'd missed. Of course the question now is can we force the module back to Class 1 somehow, as the manuals / tech notes suggest, or are we forced to rewrite the logic to take into consideration the new addresses for counter values? Do we also have ...

Hi, This is was first raised last October time at initially I thought the issue was resolved. However now that we have tried to upgrade the production line it appears we still have an issue. Whilst we appear to have configured our HSCE2 modules as Class 1 i.e. 8 Input INT, 8 Output INT, the data being ...

Hi nmeistrup, I believe we have resolved our issues but will be unable to confirm fully until we apply the machine upgrade mid-September. On migrating the SLC500 code to CLX the HSCE2 modules were automatically converted to Class 4 devices, not the Class 1 device they were originally. The data structure, ...

Hi nmeistrup, thankyou for your follow up reply. I checked the code conversion on my migrated project and it complies with example 2 however when I try to initialise the module it returns the programming error flag .PERR against the first block of data transmitted, that data having the values 1, 257,8,0,0,0,0,0 ...

Hi nmeistrup, thankyou for your reply, this will hopefully resolve my issues with the HSCE module, but it doesn't seem to answer the same question for the HSCE2 module. Is there are similar technote for HSCE2? I haven't been able to locate one to date. ------------------------------ arblakeman ...

Hi, does anybody have any experience of configuring the 1746-HSCE and -HSCE2 cards in a CLX processor? I am in the process of bringing an SLC chassis into the CLX I/O tree using a 1747-AENTR module. The code migration has gone OK but the communication class for the HSCE modules has changed and the ...
