Ionet Switches; Distributed I/O Modules - GE Mark VIe System Manual

1.3 IONet Switches

GE's Industrial Ethernet 10/100 switches (ESWA and ESWB) provide the performance and features needed in today's
real-time industrial control systems. Use 8-port ESWA or 16-port ESWB Ethernet switches in all control system I/O networks
to maintain the reliability needed for I/O module reception of controller outputs.
Note For more information on the IONet switches, refer to the Mark VIe and Mark VIeS Control Systems Volume II: System
Guide for General-purpose Applications (GEH-6721_Vol_II), the chapter Unmanaged Ethetnet Swtiches.

1.4 Distributed I/O Modules

TMR I/O Module
16 GEH-6721_Vol_I_BP
The I/O modules contain three basic parts: terminal board, terminal block, and I/O pack.
The terminal board mounts to the cabinet and comes in two basic types: S and T. The I/O
pack mounts to the terminal board J-port connector. Both terminal board types provide the
following features:
• Terminal blocks for I/O wiring
• Mounting hardware
• Input isolation and protection
• I/O pack connectors
• Unique electronic ID
