INTRODUCTIONHARDWARE DESCRIPTION1 - 2 I-E96-624A®HARDWARE DESCRIPTIONThe Plant Loop to Plant Loop Remote Interface acts as anothernode on the Plant Loop. The interface consists of three moduleson a dedicated module bus.Plant Loop to Plant Loop Transfer Module (INPPT01)This module processes incoming and outgoing Plant Loop mes-sages, buffers data and communicates with other PPT modulesin remote Plant Loops. The PPT is a double circuit board mod-ule. It has a memory board and CPU board. The user selectsgeneral operating characteristics and point definitions throughsoftware configuration. Other characteristics such as type ofcontrol (one-way or two-way), Node ID and port options areuser-configured through dipswitches on the CPU board.Bus Transfer Module (INBTM01)The BTM is responsible for translating messages from the LIMand placing them on the module bus. It also receives messagesfrom the PPT. It translates those messages and sends them tothe LIM through a direct memory access (DMA) cable.Loop Interface Module (INLIM03)The LIM provides the communication link between the PlantLoop and the PPT. It receives messages from Plant Loop nodesand monitors loop status. The LIM forwards messages from theloop to the PPT (though the BTM) via a direct memory access(DMA) cable. Additionally, it receives messages from the PPT(through the BTM) and sends them to the proper node on theloop.Additional HardwareSome applications require additional hardware such as amodem network, radio link or microwave link. This hardware isnot part of the INPPR01 standard hardware. INFI 90 DigitalSlave Modules (IMDSO01 through IMDSO04, IMDSM05) sup-port control signals to these devices.FEATURESThe Plant Loop to Plant Loop Remote Interface provides com-munication between a local loop and one or more remote loops.This interface has user selectable control modes. Selecting theone-way mode enables a local loop to receive exception reportsfrom up to 32 remote loops. In the one-way mode, only thelocal loop can initiate control commands. The two-way modeenables bidirectional control and exception reporting between
