About the gateways
The Softing Modbus Gateway offers robust data mapping between a Modbus TCP server and a PROFIBUS
master for easy connection of PROFIBUS network slave devices to a Modbus control system.
The
mbGate PA
is available as a 2-channel model and a 4-channel model. Both models integrate
PROFIBUS PA (
P
rocess
A
utomation) networks in Modbus systems at a fixed speed of 31.2 kbit/s. The
2-channel model supports up to 32 PROFIBUS PA devices and the 4-channel model up to 64 PROFIBUS
PA devices. This gateway is typically used in areas of process automation with explosive atmosphere.
The
mbGate PB
integrates PROFIBUS PA (
P
rocess
A
utomation) and PROFIBUS DP (
D
ecentralised
P
eripherals) networks in Modbus systems at speeds of up to 12Mbit/s. It maps two PROFIBUS PA and
one PROFIBUS DP network segments supporting up to 32 PROFIBUS PA and 32 PROFIBUS DP devices.
This gateway is typically used with a centralized controller in factory automation.
The
mbGate DP
integrates one PROFIBUS DP (
D
ecentralised
P
eripherals) network with up to 32
PROFIBUS DP devices in Modbus systems at speeds of up to 12Mbit/s.
All three gateways support industry-standard device configuration, parameterization and condition-
monitoring tools.
Engineering systems and asset management systems
The Modbus Gateway can be managed with the following tools:
Modbus engineering system (e.g. Schneider Unity Pro, Siemens TIA Portal)
FDT frame application (e.g. PACTware)
Siemens SIMATIC PDM (Process Device Manager)
2.1
Intended use
This series of gateways has been designed to integrate PROFIBUS network slaves in Modbus TCP networks.
Any other use is not intended. Follow the instructions in this document on how to configure and operate
the gateways.
CAUTION
Do not use this device in hazardous areas! See Section
