Perform the following steps to disable extended MEWTOCOL commands for FPWIN Pro:

1.Locate file "NAiS_MewPLC.DAT" under C:\Program Files\NAiS MEWNET

2.Open "NAiS_MewPLC.DAT" with a text editor, e.g. Notepad

3.Find the section for your PLC, e.g. [FPSIGMA] or [FP2]

4.Set the parameter EXTCMD=0 to zero

5.Save changed file "NAiS_MewPLC.DAT"

6.Restart FPWIN Pro

13.1.1Details of the IEC 60870 Configuration: Modem and Multipoint Settings

1.) Multipoint with FP Modem-EU

•line parameter: half duplex 1200 bps (independent from the RS232C baud rate)

-communication via V.23 mode 2 norm via twisted pair cables

-terminator: see manual of FP Modem-EU

•modem setup: initialization with PC and terminal program

-set all DIP switches of the modem to OFF and connect to the PC

-set the terminal to 1200 bps, 8 data byte, parity ODD and 1 stop bit (see note 1)

-Use the terminal to reset the modem to AT&F&W

-store the settings of RC232 format (see note 1)

-AT*W=1200,8,O,1

-set modem DIP switch 2 to ON

•connect the modem to RTI (RTU) via the standard modem cable 1:1

•RS232C signal (PC mode): DCD shows status line, i.e. line is busy

•RTS initializes sending: CTS after RTS means OK to send

•Settings for RTI (Lian98 from Ver 1.0.1.2 onwards):

-baud rate, data byte, parity, stop bits set to same values as the modem (* Note)

-timeout 280ms minimum

-modem: half duplex

-transmission: unbalanced

•Settings of RTU (IEC Communicator):

-baud rate, data byte, parity, stop bits set to same values as the modem (* Note)

-handshake: RTS/CTS
