Base on my short experiences when execute several automation project, I would like share how to make the instrumentation wiring diagram. The main concept that needed to be understand when make instrumentation wiring diagram is we should ensure there is no noise that disturb the signal from field transmitter and to field actuator. Control loop’s actual performance of automation system will affected when signal transmission from/to actual field instruments are disturbed by noises. Several sources of noise that needed to be considering are:

ADAM-5510KW/TCP is PAC (Programmable Automation Controller) base on IEC-61131-3 standard package. IEC-61131-3 is the third part of open international standard IEC 61131 for graphical and textual PAC programming languages. Base on IEC-61131-3, PAC should support these programming languages :
With the IEC-61131-3 standard package, ADAM-5510KW/TCP support for comprehensive controling distribution, processing data and have more capability than old PLC function. Moreover, ADAM-5510KW/TCP also support with modbus TCP (Server/Client) and RTU (Master/Slave) protocol. These standard open protocol enable ADAM-5510KT/TCP to communicate with other device.

On this chapter I will show you how to configure Wonderware ArchestrA 3.0 to control and monitor 2 or more PLC SLC500 via TCP protocol. Before that, you should have already install :
Microsoft XP Professional Service Pack 2 - minimum operating system
Microsoft SQL Server 2005 Service Pack 2 - repository database when running ArchestrA application
Wonderware Intouch 10 - main template to insert ArchestrA symbol libraries
Wonderware Application Server 3.0 - develop the ArchestrA symbol libraries
TCP Driver Communication - setting IP address SLC500 and mapping address between tagname HMI and memory address PLC (on this case I use DAServer : DASABTCP 1.1 SP2)

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.
