Morning, You could use indeed a CP343-1 Lean card wich is the basic version of the CP343 but it's still very expensive and probably not available at all at the moment. A cheapest solution is to use an Ethernet/Profibus gateway (yes another gateway ;-)) like this one : https://www.ibhsoftec.com/epages/63444704.sf/en_GB/?ObjectPath=/Shops/63444704/Products/20266 I never used it but IBH is well known for their compatible Siemens products. JC

Morning, You have to download the GSD file of your device (it's a small text file) and install it in the HW Config. JC

Either you change your meter for one that can communicate as a Profibus slave or you use a Profibus/Modbus RTU gateway. You can have a look on Anybus or Hillscher products. In any way forget Modbus with Step 7, it's expensive as you need a CP and it's really complicated to program, you can trust me :) JC

Hello, Modbus and Siemens (at least with Step7) it's the wedding of the rabbit and the carp as we say in France So if your Proface has another RS485 port, it wil be easier to use the HMI to communicate with the meter. JC

Morning, Second line is correct cause the test of the input is made before the launch of the event code (EVTx) so for me you don't need to do it eventually. It has to be tested anyway because as I said before I never used these events. JC

I have understood what you want to do. Events could do the job but it's more limited than FAST task. By example, in configuration, you double clic on blank square "function" and you choose falling edge of the input filtered at 1ms and the event you want to use, here EVT0. I add a picture, it's in french but it's esay to see what to do. JC

Morning, I have used micro and Premium PLCs for years and I never used events. For fast treatment you better use the "FAST" task. Its cycle time is 5 miliseconds or less (up to 1 ms) if necessary. You can associate inputs and/or outputs to this task. Be aware that by configuring a short fast period you affect the mast task. The shorter is the FAST period the longer will the MAST task. JC

Morning, I had the same problem with more or less the same cpu and even with the software I could not remove the simulation mode that desactivate the outputs. Program was running but without the outputs it was just a very poor christmas tree... The constructor send us back a new processor, we put the memory cartridge into it and it was ok. We didn't understood why this cpu went in simulation mode by itself. This generation of Hitachi plcs was very weird. JC

Hello, Do you have the software to connect the plcs ? what about the source code ? From what I see you have lost the program but it's an hot standby system and I'm not familair with this architecture. Anyway you need to connect the plcs according the hot standby manual to look what is wrong. JC

Hello, According the size of your program you need a 32K or 64K flash eprom pmcia cartridge. Reference are : TSX MFP 032P (old ref) TSX MFP P128K (new ref) TSX MFP 064P (old ref) TSX MFP P224K (new ref) You need PL7-Pro to tranfer the program into the cartridge and then you don't need battery anymore. But you can noyt modify the program in run mode with this type of memory cartridge. JC Hola, Según el tamaño de su programa necesita un cartucho eprom flash 32K o 64K pmcia. Las referencias son : TSX MFP 032P (antigua ref) TSX MFP P128K (nueva ref) TSX MFP 064P (antigua ref) TSX MFP P224K (nueva ref) Necesita PL7-Pro para transferir el programa al cartucho y luego ya no necesita batería. Pero ahora puede modificar el programa en modo de ejecución con este tipo de cartucho de memoria. JC

Morning, I never saw an excel tool to calculate cpu load for Siemens S7-300/400 Plcs. The only thing you could do is calculate yourself by adding instructions time for each instruction of your program according to your processor. Its a titanic job that is completly useless because I doubt you will ever meet a cpu load issue, except if your program is absolutely gigantic, and gigantic is weak :) JC

Morning, Replacement drive is Lexium 32 but you should be advised that it's not a straight forward conversion. Electric connections are slightly different and if you have a communication between the drive and a plc in canopen or other networks you need some modifications in the plc. JC

Hello, One of our customers has several machines equiped with ABB CS31 plcs. We have KT92 and KT93 types. I have tried to upload the program from an KT92 to see how it works. I have used 907 PC 331 under windows. The transfer start but can not be achieved, each time I tried, I got an "read error at word number 1912" message and the transfer is stopped with an uncomplete upload. So I wonder now if I have used the the right software ? if yes, should it be used under Windows or on a true DOS machine ? at last I have some troubles to get some informations about ABB plc in France, specialy for the cable needed. I have made one with a drawing I found on Internet but i'm not sure it's the good one so if someone has the correct drawing please let me know. Thanks JC

Hi, here is the pogram in pdf. Hope it will help. JC Econo5.3.pdf

Morning, Thanks, I should be able to do the job with this tips.   JC

Hi, I need to upload a program from a PLC-5 5/15 plc. This plc is fitted with a communication card that should allow to communicate in DF1. I don't know the reference of the card but my customer sent me a picture. So as i'm not familiar with Rockwell products I would like to know if I can comunicate with it whit a simple null modem cable in DF1 and if yes is there's something I should know to configure RSLinx or is it the same procedure than the processors with built in DF1 port ? Thanks JC

Morning, You have lost the program for sure. There's a battery inside the RAM cartridge  memory and if it has never been replaced the program vanish each time you power off the plc. JC

Morning, You can use either a Westermo MA-21 RS232 / current loop converter which was the converter used by Telemecanique under the name TSXTE01 or a more recent Schneider cable called FT21CBCL030. A TSX 67-425 processor is programmed in PL7-3 but for a complete backup you have to use the transfer tool available in a V5 station.       JC

Hi, To be exact, Unity Pro software (used for M340, M580 plcs) is not based on Codesys. EcoStruxure Machine Expert (formerly known as SoMachine) used for Modicon M241, M251 etc. is actualy based on Codesys. JC

Morning, You need PL7-3 software included in XTEL software package. This software runs under OS/2. A VM can be used without any problem even with a laptop without com port. In this case you have to use an usb-serial converter as com1. To connect the plc you need and RS232-Current loop converter, idealy a Westermo MA21 converter which was the one used by telemecanique. However you can use any converters like the one in the attached picture. JC

Morning, The Serie 7 Telemecanique plcs was composed of TSX17, TSX27, 47, 67, 87 an 107. The connection cable needed for a 17 is a RS232 to RS485 converter. Standard converter may be used. All the others need a RS232 to current loop converters. In the software there was PL7-2 for TSX 17, 27 and some 47 and PL7-3 for others 47, TSX67, 87 and 107. PL7-2 and PL7-3 existed in DOS and OS/2 version. Under OS/2 these software were included in a pack called XTEL. Forget the DOS version it's useless. I can give you a Virtual image including XTEL and PL7-2. I can give you as well the drawing of the cable. Now if you feel you can manage with it let me know by pm. JC

Hi, If you realy have an eeprom cartrdige (located near the language PL7-2 cartridge) you have the program inside, so you just have to swap it into a new plc and that's all. Of course it could be interresting in addition to connect the plc to upload the program to have a backup on pc.   JC

Hi, TSX is a generic name and means nothing, what is the reference of your plcs ? JC

Hi, You can try here : http://mei-msma.fr/crbst_43.html if it doesn't work, let me know by pm, I have others versions. JC

Hi, Are you talking of a TSX 47 plc from Telemecanique programmed in PL7-3 ? If so there's no software that could be used in any Windows version. You must use PL7-3 software either under DOS or OS/2. An other alternative is to use a T407 console with the PL7-3 langage cartridge but it could be difficult to find one. JC
