(1) Transmmiting a lot of signals using two-wire cable. (2) DP addresses are used for diagnostic etc, I Q addresses determines signals to be transmitted. (3) Read SIMATIC NET Communication manual. (4) Insert another master in network, then you will see why. (5) No relation (6) At Siemens site, Automatation -> Communication -> Profibus -> Manuals

Try this: Put you alarm bits in DB0.DBW0. This are the real alarms (comes OFF after reset). Define another word DB0.DBW10. Execute always DB0.DBW10=(DB0.DBW10 OR DB0.DBW0). Then in MP277 define an alarm class LoggedAlarms. Define an discrete alarms From DB0.DBW10 as LoggedAlarms.. Then use a one AlarmView to show LoggedAlarms class ONLY. Then you can reset LoggedAlarms from times to times using DB0.DBW10=0000h.

Hi! You can not 'downgrade' application. You must write application from a new. First be sure that your application do not use features availble only on V2, and if it is the case, see what you can do avoid using it. TIP: You can copy screen elements from V2 to V1 to save a work efforts.

There are no FCBs in MicroWin. To copy network(s), select the network(s) first, by clicking on the vertical 'strip' in LAD editor at the left of the network(s) to be copied. Then CTRL+C to copy network(s).

Hi, Marko! I do not think so. As you can see in CX-Designer, only CJ1/CS/CV/CJ2/Trajexia can be selected as a host using Ethernet communication. Pozdrav/best regards!

Crossbow, noone helped me. I asked about cable, they tell me about port. And, what's wrong with my tone?

Hi! All configuration and data are ALL in CPU. Read manual to see how to define data areas. Do not forget to define a CLK address using switch on CLK21. Do not forget to turn on proper AR bit to start datalink (on CQm1H machines). Best regarsd!

Hi, Cross! As you can see, there are al least four ways to make a serial cable. I wanted someone with expirience help me selec cable to spare my soldering efforts. No problem if you do can not help me, just be quiet. Regarding ethernet comm, it is clear, it is simple, but it is not challenge. :) I have here two S7-1200 with RS232, I have time to spend, so why not try Modbus? Someday maybe I'll need it, and then I will not have to spend pecious time to experiment with this. I repeat, if someone DOES NOT know answer to my question, NO PROBLEM, but do not try to write about something different. I am sick of 'geniuses'. :) Best regards. Untitled-1.pdf

What is this? Gestapo questioning? I just want to know cable pinout....

No, just wired, 3m distance.

Hi! What about firmaware versions of S7-1200 and version of TIA portal? It is new software and its it depeneding of new firmware releases What is your TIA version and firmware version of S7-1200?

Hi, Lubomir! Open a new project. Put both PLC's in the same project (PLC1 and PLC2) Doubleclick on PLC2 In Network type, choose (PLC1) - to make it a Gateway for connection to PLC2. In settings, choose Node address and Unit No od CLK board you have in PLC2. Thats all. Once i worked wtih 11 CQM1H/CJ1 (with CLK units) and I was able to open ALL 11 PLCs (simulaneously ONLINE) when connectes to first PLC via serial cable only. Thats great.

Yes, using Modbus protocol and included libraries.

Be aware of module address setting (switch). With 16-bit modules you must pay attention to even/odd module addresses. Read manual carefully.

1. Try to disconnect load (all outputs disconnected) and then try to monitor. 2. Port settings? Did you change SM area?

Which one 313C you have? 6ES7313-XXXXX-YYYYY?

Hi! See Omron manual Cat. No. W421-E1-04: Ethernet Units - Construction of Applications Best regards

Or, you can connect various PLC-s using Anybus wired gateways (or Weidmuller/Elpro wireless gateways). Easy, transparent....

Yes, it's allowed. All PLCs can also excange data via GPRS.

Hi all! As I know, S-200, S7-300, S7-1200 can communicate with Sinaut Micro SC via GPRS. But, is it allowed to combine different PLC types (S7-200, S7-300. S7-1200) in THE SAME Sinaut Micro system? Thanks.

Hi all! Is attached configuration correct? Please answer experts/expirienced ONLY. Do I need a CP card in PC Stations, or use a standard Ethernet port? If I must use CP card, will then Sistore software access IP cameras through CP card? Best regards and thanks in advance Siemens_konfiguracija_2010_07_20.pdf

As Axel said once, 'Chinese democracy'.

I do not care if someone steels from me, my 'intellectual property'. First, i will not live forever, second, there is always someone who can do what I did. When I make a machine or plant control, I ALWAYS leave ALL unlocked. So, anyone interested can see what I did. Maybe they will learn, maybe they will laugh.... Customer has paid ONCE for my work, no need to pay for it again.. There are other works for me...
