13.1.1 Details 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
