The Smart-3G Ethernet Programmable Controller (pn 5732P) provides networked 24volts Digital I/O for MDR Powered Roller Conveyor systems, as well as general purpose Fast Local/Remote Machine I/O. These Devices are fully programmable for any type of control application, and can act as a programmable master device, or a slaved network I/O device. The modules communicate over Ethernet to master or peer devices using Ethernet/IP, Modbus/TCP, Profinet(in development) and S3G-Master/Slave protocols. For MDR systems, interlocking messaging bits e.g., upstream, downstream, merge, divert, etc are handled by the firmware for simplified Ladder Logic Programming.
The Smart-3G cards are programmble using Ladder Logic. In addition, these cards can act as remote I/O for master PLCs or PC software. By selecting Remote-I/O checkbox in configuration, the card acts on I/O commands received from the master PLC, and does not execute any local ladder program.
These cards are well suited for distributed I/O system. Each card can have its own ladder logic program for I/O control, and can talk over ethernet to exchange I/O messages.
For centralized I/O, one card can act as master controller and controls up to 8 other slave Smart-3G cards, which act as remote-i/o. The Remote-I/O cards inputs and outputs become local I/O on master controller. This method allows easy debugging and use only one ladder logic program for the whole system.
