ADAM-4056S is a 12-channel sink type isolated digital output module for critical applications. The open collector output can provide voltage from +5 to +40 V and the status reading output could see on the LED indicator. On this article, I would like share my experience on communication between ADAM-4056S and Visual Basic 6.0. Although ADAM-4056S support for ASCII and Modbus/RTU protocols, on this article I just explain for ASCII protocol. Continue Reading »

This system working very well to perform the analog data acquisition (temperature) from many RTD to PLC SLC500 Allen Bradley via ADAM-4015, PROLINK-5201/5202-MNET-MCM(4) and PROSOFT-MVI56-MCM. The advantages of this acquisition system are: we could cost-down the using of analog cable, possibility of high speed data transfer until 100 Kb/s - 10Mb/s for long distance way (approximately until 1200 meter), possibility using redundancy concept to optimize and validate data collection from field instruments, reduce the complexity of analog cable installation and noise from unwanted signal (induced noise, ground level differences, impedance mismatches, failure to effectively bias for idle line conditions). You know that analog signal very sensitif from noise. Continue Reading »

Began on past March 2008, I am join with Automation Engineering Division, PT. Sinar Inti Electrindo Raya as Automation Project Engineer. Before that, PT. SIER had the several automation project, such as 50 TPD (Ton per Day) Biodiesel Plant in North Jakarta, SCADA (Supervisory Control and Data Acquisitions) in IKPP Riau and Crushing Area and Barge Loading for KAYAN in Kalimantan.
