1.    Overview

HV-GSM is a wireless data transfer communication module, adopt Modbus-TCP protocol, can be 
used in automatic system matched with High Value series PLC to realize wireless connection 
between automatic system and GPRS, GSM net. Basic on this module, you can upload and
download program to realize remote compilation and diagnosis for PLC by using host software configuration of HV series PLC. At the same time, mobile phone user can control PLC by using SMS service. Thus, HV-GSM is suitable to be used in distributed system, remote monitor and relative situations.
