This project involved several different technologies to enable the success of this. The driver for this project was the requirement of high visibility in a manufacturing plant environment.\u00a0 The large digital displays were chosen for their large readable displays to be seen on the plant floor.\u00a0 A countdown timer for manufacturing processes was requested. Each station on the assembly line has a specific time allotted for an assembly operation and at the end of the time slot, a notification such as a buzzer was energized.\u00a0 As I investigated the large displays I found that the primary means to communicate information to the displays would be RS232 or RS485.\u00a0 After studying the capabilities of the PLC I decided that an RS485 network had the greatest chance of success.\u00a0 The communication link from the PLC port adapter to the large digital displays was ethernet cable connected configured as an RS485 network.\u00a0 The PLC used a real-time clock to create a time system based on calendar days, days of the week, hours minutes and seconds.\u00a0 The PLC program used ladder logic to address each digital display individually to update the time down count.\u00a0\u00a0 The Micro HMI was programmed to enable recipes for various time down sequences depending on the particular product being built on the assembly line.\u00a0 The relay outputs on the PLC were used to power the timer group on at beginning of work shift and power off at the end of work shift.\u00a0 The PLC outputs were also used to stop the timing sequence during breaks and lunch period.\u00a0 This project performed in an excellent manner and exceeded expectations.<\/p>\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t I use this PLC because it has universal inputs for sourcing and sinking and relay outputs so that almost any combination of inputs and outputs are usable.<\/p>\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t This is a large Digital Display.\u00a0 The numerals are 3\u00a0 inches high and visible across the plant.<\/p>\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t This Port Adapter will enable the register commands in the ladder program to convert to RS485 signals that will carry time information to the digital displays.<\/p>\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t The Micro version of the C-MORE HMI will load the registers with the predetermined recipe for each time down sequence depending on which time is required.<\/p>\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t This project involved several different technologies to enable the success of this.
