PfofiBus Gateway
1. Overview
1.1 ProfiBus Gateway Unit
The ProfiBus Gateway Unit (hereinafter referred to as “ProfiBus Gateway” or “Gateway Unit”) is used to
connect a ProfiBus communication protocol network on which a host programmable controller (hereinafter
“PLC”) operates, to a SIO communication sub-network (Modbus communication protocol) linking ROBO
Cylinder controllers.
The physical standard to which the SIO communication network conforms is RS-485, and the slave
addresses on this network are 1 through 16.
All data exchanged between the ProfiBus communication network and the Modbus SIO communication
network are tentatively saved in the internal memory of the Gateway Unit, and then transferred cyclically.
The PLC recognizes the Gateway Unit as a remote I/O device.
The Gateway Unit supports PCON-C/CG/SE, ACON-C/CG/SE, SCON-C and ERC2-NP/PN/SE
controllers.
* “Gateway” is a term used in communication networks, referring to a device that converts data to/from
different media and protocols to enable communication between networks.
* ProfiBus protocols include ProfiBus-DP for factory automation (FA) and ProfiBus-PA for process
automation (PA). Of these two protocols, this manual covers ProfiBus-DP. Accordingly, “ProfiBus”
refers to ProfiBus-DP throughout this manual.
Caution
This manual only describes the controls feasible using the Gateway Unit. In the event of any conflict
between this manual and the operation manual for the controller, the content of this manual will
prevail. Refer to the operation manual for each controller for any function, parameter setting, alarm
detail or any other information not described in this manual.
