Note
The MD720-3 modem is used not only in SINAUT ST7 but also in SINAUT MICRO SC. In
this case, S7-200 stations can transmit data over GPRS using the MD720-3.
Along with the Ethernet TIMs as of firmware version V2.0, the MD720-3 can also transmit
data via GPRS in SINAUT.
In a station, the MD720-3 can be connected to the RS-232 interface of a suitably equipped
TIM module:
●
When using CSD: All TIM 3V-IE and TIM 4 variants
●
When using GPRS: Connection to any Ethernet TIM
The cable for connecting the MD720-3 must be ordered separately with a TIM.
The MD720-3 can be installed on a 35 mm standard rail.
