IEC 60870 functions of the FP Web-Server
164
FP Web-Server V2.810 EN
Using IEC 60870 communication the PLC needs to execute
special IEC 60870 function blocks. These PLC function blocks are
delivered as an FPWIN Pro library together with the FP Web
Configurator Tool. The IEC 60870 FPWIN Pro library,
accompanying examples and interoperability documentation can
be installed from the FP Web Configurator Tool CD-ROM. For
details refer to the Library's online help (see p. 167).
The "IEC 60870" tab will be enabled in the FP Web Configurator
Tool (versions 2.16 and higher) after you have entered the
license code and installed the FP IEC60870-Library.
If the IEC 60870 functions are to be used (check box "Enable
IEC60870" is active), disable standard FP Web-Server's functions
like http, e-mail, PPP server or port function (see p. 123). If
these standard functions are enabled at the same time as the
IEC 60870 protocol, the reaction time and performance of the FP
Web functions may slow down.
If the 9-pin RS232C port is set up for IEC60870-5-101
communication, MEWTOCOL communication can take place. The
IEC60870 polling from the central station must be stopped
before MEWTOCOL communication can be used. MEWTOCOL
commands are sent directly to the PLC. This version only allows
short (standard) MEWTOCOL commands.
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
