IEC 60870 functions of the FP Web-Server
FP Web-Server V2.810 EN 165
terminator: see manual of FP Modem-EU or FP Modem-56k
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 1200bps, 8 data bits, 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 bits, parity, stop bits set to same values as the
modem (see notes)
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 (see notes)
handshake: RTS/CTS
mode: Multipoint-party line
Parity even and a baud rate other than 1200bps are only available
from FP Modem-EU firmware version 1.23 onwards (use ATi3 to
display the version), or use the FP Modem-56k instead.
The same baud rate is recommended for RTI and RTU.
Multipoint communication with the FP Modem-EU and FP Modem-56k is
compatible with standard industrial multipoint units.
