MX4 Scada

[Wile E Coyote]

Could someone tell me which is the best communication method to use in GX-Developer when using a QJ71E71-100 ethernet module connected directly to a pc. MC Protocol, Fixed Buffer Comminication (with procedure exsist control method), Fixed Buffer Communication (with no procedure control method), or Communication using the Random Access Buffer? Thanks in advance

Hi.Melsoft Connection.

Since your topic is MX4 Scada I guess you mean MX4 (instead of GX Developer) to a QJ71E71-100. Just set to TCP Unpassiv Receive procedure exists Disable confirm <port nr> This would be the correct settings for MX4 scada(Citect) Note. The host station port number set in the open settings in GX Dev is in Hex in MX4 it's in DEC.!!!!!!! Edited September 18, 2008 by Gambit
