Modbus ASCII Protocol between ADAM-4056S and Visual Basic 6.0

Published under Control System,Industrial Network

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 [...]

Modbus RTU Protocol between ADAM-4015 to SLC500

Published under Industrial Network

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 [...]
