hello....yesterday i have try to sending and read the msg from PLC by a simply programming. But the data i receive back is in unknown form. So i guess is my baud rate problem, from the modem manual book it's ask me to use factory setting where bps=115200, data bits=8, parity= none, stop bits= 1, flow control= hardware. But in PLC i only can set in FX parameter by following: protocol=non procedural, data length=8, parity= none, stop bits=1, and bps=9600. Am i set wrongly in FX parameter? Is that the baud rate for modem and PLC not match therefore the data i receive is in unknown form? and how can i solve this problem to let the data i receive back convert to hexadecimal form? Thanks.

hi...need for urgent help!! i'm using FX1N PLC and work together with Wavecom Fastrack M1206 GSM modem. Before that, here my project brieftly. I would like to get an msg when X0 push button are press and Y0 LED are light on. In order to let me know X0 are running. Beside that, i would like to remote control the Y0 by sending a msg back to GSM modem and tell the PLC switch off the Y0. But i have try for many many times, i still cannot get the msg when the push button are pressed. So i here to ask for advice from who know this programming. Here is my problem: 1) Is that i need using parameter to set the baud rate,parity and etc? 2) Is that i need to put the STX and ETX before and after the message i set to send? 3) I also would like to know how to know the length of device memory (k)? is that count by column? means if i use 10column, i put k10? And i also want to know, is that anyone have example for me to refer on? Thanks Brandict.
