GK panels do not use MEWTOCOL monitor commands.
• To eliminate the problem of only one client being allowed to use FPWIN Pro or FPWIN
GR for data monitoring, permit only one client. See the parameter MEWTOCOL Number
of Clients.
• MEWTOCOL communication between a PLC and FPWIN Pro (or an FP Web-Server
port client or GK panel) can involve a very high data load, i.e. with a single FPWIN Pro
client, communication can be hindered so gravely that http pages and email
communication are slowed down significantly.
• While MEWTOCOL multi-frame communication (program download) is being executed,
MEWTOCOL communication for the other clients (including email and http functions) is
temporarily stopped!
8.1.2 Client's Side
At the client's side (computer, GK panel or an FP Web port client) there are several possibilities
and/or software packages to communicate with the FP Web-Server's MEWTOCOL server port
(to exchange data with the PLC):
a) With FPWIN Pro, GTWIN or PCWAY it is possible to communicate directly with the
FP Web-Server, i.e. the PLC/ GT10 or GT30 via the Ethernet.
The following settings are required:
Do not activate the check box "Use ET-LAN unit"!
b) With GKWIN version 2.0 it is also possible for a GK panel (GK30 or higher with a
built-in Ethernet card) to communicate directly with the FP Web-Server.
