FBs-1LC Fatek Load Cell input module...

Introduction

FBs-1LC is one of the analog input modules
of FATEK FBs series PLC. It can connect
one load cell input for weight measurement.
The conversion result is represented by a
signed 16 bit integer value. In order to filter
out the field noise imposed on the signal, it
also provides the average of sample input
function.

Using Fiber Cams for timing and positioning......

The use of Cams is very common and easy for the positioning and timing setting for a moving shaft. It is the manual and the cheapest method for this application instead of using the digital shaft encoder. For Example if we look at the example of Packing machine when we want to sense the blank faulty packet of the soap on a specific angle or position of the shaft. Then we have to use encoder for this application i.e when the shaft is on at that angle the sensor sense the packet at that time only of that specific angle or position.

So, for this purpose we use encoder but if the timing is much more i.e 5 or 6 we can easily use a fiber cams for setting up the timing instead of a encoder. The main advantage is also that we can use the fiber cam with normal sensor i.e metal detector and can easily be connected with the normal input of the PLC, there is no need of any High speed input or High speed counter for the software to use this.

Well, the parameters used for the above mentioned setup for the plc program will that the sensor of the Cam will be our INBIT and the sensor of the fault i.e packet sensor will be the DATA BIT and then the both will generate the pulse at the same time the plc will start counting and will reject the packet at required counting of the shaft from the cam. For this, we use SHRB function in Siemens step 7 PLCs. The program example for this is also given below.

Wonderware HMI/SCADA

HMI/SCADA solutions often impose complex demands on software architectures. Wonderware InTouch HMI Visualization, coupled with the award-winning ArchestrA-based Wonderware System Platform is uniquely positioned to meet these challenges.

Solutions built on ArchestrA technology benefit from a single, open and scalable software architecture that can connect to virtually any automation system, remote terminal unit (RTU), intelligent electronic device (IED), programmable logic controller (PLC), database, historian or business system in use today. The open nature of this platform enables users to expand their existing systems without having to buy new hardware or control systems.

Geographically dispersed applications, from a few hundred to one million I/O and from a single node to hundreds of stations, can be rapidly and securely implemented.
