Re: [?]: conect Data acquisition modules adam-4019+ to plc 3

Looks like ADAM module doesn't answer or there is a wrong wire connection. I don't know what data you are sending to it. Have you checked the ADAM manual how to construct character frame?

Re: [?]: connection between PC <---> cpu 224

I suppose that PLC port is set to baudrate of 187,5 kb/s, as there are no devices connected to it. CPU 224 supports baudrate up to 187,5 kb/s. The bad news is that you can't connect using old RS-232/PPI cable. You should use RS-232/PPI Multi-Master or USB/PPI Multi-Master cable or PC Adapter USB or ...

Re: [?]: connection between PC <---> cpu 224

Hi PLC_ITA,
Just find a proper time to switch PLC to STOP (during plant maintenance for example).

What peterc101 wrote is correct.

Are there any devices connected to the PLC port?
It could be used for USS communication to VSD (variable speed drive).

Re: [?]: connection between PC <---> cpu 224

The comm port(s) of S7-22x CPUs can operate in 2 modes: PPI and freeport.
If the port is set-up for freeport communication you can't connect using PPI protocol and MicroWin.
But the good thing is if PLC is in STOP, it automatically switches port to PPI mode, so try to connect when PLC is stopped.

Re: [?]: conect Data acquisition modules adam-4019+ to plc 3

There are few different ways to do it: 1. The easiest way is to use ASCII communication. You need a CP340 (RS 422/485 version) at S7-300 side. You should configure ADAM module for ASCII communication. There is #AAN Command to Read Analog Input from Channel N of ADAM Module. Check the ADAM Manual htt...

Re: how simulate sercos interfase

You can't simulate Sercos interface as I know. It is too complex, but if you need to simulate axis movement, then you can use AXIS_VIRTUAL insted of AXIS_SERVO_DRIVE.

Re: ?:Safety when Manual-Automatic selection is from 2 locat

Hi nashama, Don't you think in this case you should not be able to select even Manual mode from HMI/SCADA for better safety? I mean what if you are in the field at the electrical cabinet with Manual mode selected and at the same time some one reaches to the HMI and accidentally makes any "Manual" mo...

Please Ignore my previous post. I made a copy/paste mistake (sorry) .

Re: CPU 400 on MPI

The error message you receive is for time synchronization on MPI interface of S7-400. it is nothing about Global data. You have configured S7-400 as time master on MPI Bus with "No time interval", which is wrong. Either disable Time synchronization on MPI or configure synchronization interval at Tim...

Re: Есть ли функция для инвертирования аналогового сигнала?

You want to inverse scaling as I understand.
Here is the sample code if the scaling is UNIPOLAR.

Do the following:
in STL:

Code: Select all

      L     27648
      L     "Output from FC106"
      -I    
      T     "New Output"
or
in LAD:
use SUB_I instruction to subtract "Output from FC106" from 27648.
