SCOPE Solid AT's 2-wire devices are suitable for tough and corrosive environments. Until now the Solid AT 2-wire devices had to be monitored locally. The new remote display solutions provide the user with the ability to monitor a 2-wire device from a distance and thereby let the user enjoy the benefits of cost effective 2-wire remote display solutions. This document provides an introduction to four remote display solutions for 2-wire devices over a 4-20mA current loop by a third party. 2. OBJECTIVES • Familiarize the user with the ABB C50 remote display solution. • Familiarize the user with the ABB C150 remote display solution. • Familiarize the user with the ABB 695FI remote display solution. • Familiarize the user with the Shimaden SD16 remote display solution. 3. SOLID AT DEVICE OPERATION USING A REMOTE DISPLAY The advantage of a remote display is often necessary for plants that don't have a PLC or a controller to monitor measurements. In order to observe the measurement value on the gauge's display, the user needs to climb on the vessel. Often the vessel is located far away from the control room. Continuous measurement is often required in order to follow the process, maintain a fluent storage data base and/or to monitor process failures. Remote display gives the user an efficient solution to observe the measurement on the remote display device while using the 4-20mA current loop. A remote display module enables the user to upgrade a 2-wire mono block device to a ‘two-part system device’. Although the 2-wire device cannot be programmed by the remote display it can be installed far from the device it self for monitoring purposes (4-20mA protocol specification/HART/MODBUS RTU). The remote display enables operation of pumps and other auxiliary equipment while __________________________________________________________________ AN0024GE Rev: - 1.00 Page 3 of 12 © Copyright Solid Applied Technologies Ltd. using internal relays (if specific model supports relay operation). Communication protocols are necessary to make a communication network more efficient. Using remote display with integrated Hart\\\\MODBUS protocol enables the user to implement multi drop connection while establishing a wide range network over computer\\\\PLC systems. Also, connecting a remote display to a 4-wire device like SmartScan®, will give the user the ability to monitor the process from two different locations while enjoying both the benefits of the SmartScan® and the remote display. ¢ Note: Remote Display's input can be connected only to Solid AT device's 4-20mA current loop or 4-20mA output (4 wire device). __________________________________________________________________ AN0024GE Rev: - 1.00 Page 4 of 12 © Copyright Solid Applied Technologies Ltd. 4.
