IEC 60870 functions of the FP Web-Server164 FP Web-Server V2.810 EN Using IEC 60870 communication the PLC needs to executespecial IEC 60870 function blocks. These PLC function blocks aredelivered as an FPWIN Pro library together with the FP WebConfigurator Tool. The IEC 60870 FPWIN Pro library,accompanying examples and interoperability documentation canbe installed from the FP Web Configurator Tool CD-ROM. Fordetails refer to the Library's online help (see p. 167). The "IEC 60870" tab will be enabled in the FP Web ConfiguratorTool (versions 2.16 and higher) after you have entered thelicense code and installed the FP IEC60870-Library. If the IEC 60870 functions are to be used (check box "EnableIEC60870" is active), disable standard FP Web-Server's functionslike http, e-mail, PPP server or port function (see p. 123). Ifthese standard functions are enabled at the same time as theIEC 60870 protocol, the reaction time and performance of the FPWeb functions may slow down. If the 9-pin RS232C port is set up for IEC60870-5-101communication, MEWTOCOL communication can take place. TheIEC60870 polling from the central station must be stoppedbefore MEWTOCOL communication can be used. MEWTOCOLcommands are sent directly to the PLC. This version only allowsshort (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 MEWNET2. Open "NAiS_MewPLC.DAT" with a text editor, e.g. Notepad3. Find the section for your PLC, e.g. [FPSIGMA] or [FP2]4. Set the parameter EXTCMD=0 to zero5. Save changed file "NAiS_MewPLC.DAT"6. Restart FPWIN Pro18.1.1 Details of the IEC 60870 configuration: modem and multipoint settings Multipoint with FP Modem-EU or FP Modem-56k Line parameter: half duplex 1200bps (independent of the RS232C baudrate) communication via V.23 mode 2 norm via twisted pair cablesN o t eP r o c e d u r e
