Allen Bradley controller programming
Budget: $1,500 – $3,000 USD
I am looking for a freelancer who can program my MicroLogix Allen Bradley controller using Modbus communication protocol. The primary purpose of the controller program is for process control and monitoring. Ideal skills and experience for this job include:
- Proficiency in Allen Bradley programming
- Strong understanding of Modbus communication protocol
- Experience in process control and monitoring
- Ability to troubleshoot and debug code
- Attention to detail and ability to follow specifications closely
If you have the skills and experience necessary for this project, please submit a proposal. Thank you.
Some points about the project. (Info on attached documents as well.)
(PUMPS)
Circulation Pump (CWP) switch over to Backup Circulation Pump (BCWP), based on fault of pressure switches.
Time based sequencing to alternate between Circulation Pump (CWP) and Backup Circulation Pump (BCWP). With adjustable time (Controlled through Modbus).
Supply Pump (SP) switch over to Backup Supply Pump (BSP), based on fault of pressure switches.
Time based sequencing to alternate Supply Pump (SP) to Backup Supply Pump (BSP). With adjustable time (Controlled through Modbus).
SP and BSP pump speed from Variable frequency drive (VFD) via 0-10vdc.
High level switch and low level switch to cutout all pumps.
(CHILLERS)
Time based sequencing of Chill-A , Chill-B and Chill-C. With adjustable time (Controlled through Modbus).
(TANK)
H2O make-up solenoid valve to close if high tank level is recognized.
