Opto 22's G4D32EB2-UPG and G4EB2 I/O processors upgrade legacy digital I/O systems to Ethernet
Opto 22 has released the G4D32EB2-UPG and G4EB2, two I/O processors which are designed to allow automation professionals to upgrade a legacy mistic or Pamux G4 digital I/O system on a serial network to operate as part of a modern, Ethernet/TCP-based control system without needing to replace or modify existing I/O or field wiring.
The G4D32EB2-UPG and G4EB2 I/O processors are upgrades for legacy G4D32RS and B4 digital I/O processors, or "brains," used in legacy mistic and Pamux digital I/O systems, respectively. When upgraded with a new I/O processor, digital I/O points on the mistic or Pamux I/O system can be accessed over a standard, non-proprietary Ethernet network, and can be included as part of a control program running on an Opto 22 programmable automation controller (PAC) or as part of a custom software application running on a PC. The G4D32EB2-UPG and G4EB2 support multiple Ethernet protocols including OptoMMP, Modbus/TCP, and EtherNet/IP, and a standard TCP/IP interface is used with Opto 22 software development kits and developer toolkits.
A legacy mistic digital I/O system can be upgraded to work with an Ethernet-based SNAP PAC System or a custom software application by replacing the original G4RS brain on the G4D32RS remote single mistic digital rack with a G4D32EB2-UPG kit. Also available is a complete I/O unit, the G4D32EB2, which is a physically identical Ethernet-based version of the older G4D32RS remote single mistic digital rack.
A legacy Pamux digital I/O system can be upgraded for use with an Ethernet-based SNAP PAC System or a custom software application by replacing the B4 brain on the G4PB32H or PB32HQ rack with a G4EB2 I/O processor. Note that the G4D32EB2-UPG and G4EB2 I/O processors do not use the mistic or Pamux protocols, but instead communicate with a SNAP PAC System or custom software application using Opto 22's open memory-mapped OptoMMP protocol. Also note that I/O system performance is different when a B4 brain is replaced with a G4EB2 I/O processor. The B4 brain is not being discontinued at this time.
