Project Description


I am looking for PIC18F2221 Based process controller with MODBUS communication where we are looking for a Robust and simple design the project consists
1)Temperature measurement on board and process temperature sensors (2 Nos)
2)LCD Display with temperature set point adjuster through +/- key pads
3)Push buttons to use control relays 4 nos by manual override ON as well as Auto ON through program
4)2 Nos of PI Contolled 0-10V output based on temperature sensors/ external universal signal (0-10V)
5)Reading 4 nos of exteral switches and interlock for relays & analogue out
6)Size of LCD 2x8 Charactors size. Any morden type LCD proposal welcome. Menu shall be controlled +/- and 2 more buttons / EASY configuration through LCD display navigation
7) External EEPROM for data storage unless required
8)RTCC required for standalone 7 day 24 hours time based on/off scheduler 4 nos
9) All IO and setpoint value shall be monitored and setpoint ,output override through MODBUS 20 registers
10)MODBUS RTU slave address shall be set by buttons navigating at LCD. Real time clock and calender values shall have unique resisters for write access from MODBUS Master

We need a schematic, C source code must use C18 OR XC Compiler
