Brief The course provides an overview of the entire Excel Plus system and its extensions and enhancements. The basic portions of the course is a complete discussion of the usage of Microcel Portable Programmer’s Terminal (MPPT) including MCEL Systems Configuration and System Programming. The course then goes into a discussion of the engineering cycle for the MCEL controllers. The course identifies the first step as the definition of the programming environment for each controller. This step involves a decision as to whether a Honeywell generated database or a custom database or a modified Honeywell database will be used for the relevant controller. This step also decides as to what Honeywell provided configuration and precoded files will be used. In the next step one learns how the point file for the controller is created. This is followed naturally by the creation of a program file for the controller using the provided editor program. The intimate connection between the point file and the program file is pointed out. The next step shows how to compile the program into an error-free executable code. This leads into the creation of an object file for the point and program file set and is ready for download into the MCEL EEPROM. A very important part of the course is to deal with the somewhat mythical function of the MPOT database. The course shows how point descriptor files are prepared and loaded into the MPOT and then later used using the Program Select function of the MPOT under the Main Menu function of Configure MCEL.

The course also shows the on-line test and checkout of the created databases. The course even dwells on the aesthetics of the engineering sequence provided by the Honeywell Engineers.
