ABB Symphony Plus SPIET800 Ethernet CIU Transfer Module
Description:
The IET800 Infinet to Ethernet Transfer module handles all communication with a host computer. The module is command driven through software on the host computer. The IET800 module receives a command from the host computer, executes it, then replies. The IET800 module firmware enables the host computer to issue commands for data acquisition, process monitoring, and process control, and to perform system functions such as security, time-synchronization, status monitoring, and module configuration. The IET800 module can store up to 30,000 point definitions.
The IET800 module is a single printed circuit board with an Ethernet daughterboard (for Ethernet communication over TCP/IP) mounted on it. The IET800 module occupies one slot in the MMU. The circuit board contains microprocessor based communication circuitry that enables it to directly communicate with its NIS21 module by interfacing to the I/O expander bus.
The IET800 module has three card edge connectors for external signals and power (P1, P2, and P3). Connector P1 connects to common and +5 VDC power. Connector P2 connects the IET800 module to the I/O expander bus to communicate with the NIS21 module. Control and data signals connect from the IET800 module to the host computer.
The IET800 module supports either Ethernet through TCP/IP or RS-232-C host computer connection. When communicating through the RS-232-C port, the module can act as data communication equipment (DCE) or data terminal equipment (DTE). For RS-232-C computer interface, the module cable connects to an NTMP01 termination unit and a process bus adapter (PBA). Two RS-232-C ports are located on the termination unit. The NTMP01 jumper configuration determines DTE or DCE operation. For the Ethernet computer interface, there are two Ethernet ports located on the IET800 module faceplate. Currently, only the RJ45 connector labeled CH0 on the front plate of the IET800 module is supported and should be used. In this case, no termination unit is required.
