PROCESS CONTROLLING SYSTEM

Six Model IMYs with Serial Communication Option are used to monitor and control the temperature of 6 ovens at a large bakery. The IMYs are located at each of the ovens in the production area of the building. The communications lines are run to an industrial computer located in the production offices.

The drawing below shows the Current Loop set-up. Each IMY is given an address and programmed accordingly (Program Module #7). A baud rate of 1200 is selected.

An application program is written, which sends and retrieves data from the IMYs.

Note: On all IM indicators, the SO+ and the +20 mA SRC are connected internally. Therefore it is not necessary to have this terminal tied to any other terminal on the unit if that unit is serving as the loop supply source.
