1 INTRODUCTION

 

This function block is an example for the communication with a BVS SC SmartCamera. The example is free of charge. Please test carefully if the FB is suitable for your application! This function block allows a communication between a Balluff - SmartCamera BVS SC-_* and a Simatic® S7-300/400 PLC.

Please test carefully if the FB is suitable for your application!  

 

The following commandos are supported:

Switch Application	Switches the application
Get Application ID	Gets the ID of the currently active application
Get Results	Gets the result container
Send Data	Sets the input data of the application
Get Camera Info	Gets the camera information
Get Date Time	Get the time stamp
Set Date Time	Sets the time stamp

                 Set Sequence Number Sets the sequence number

Please examine, which of the given functions are supported by the camera!

For each SmartCamera the function block has to be called with an own instance data block.  

1.1         General Data

Function block name:	FB50
Instance data block:	(an own instance data block has to be setup for each camera)
Invoked blocks:	SFB4 TON, SFC24
Reserved memory bits:	none
Reserved Timers:	none
Reserved Counters:	none
I/O Range	16 - 512 Byte
Invoke:	absolute
Device compatibility:	Siemens Simatic® S7 300/400

1.2         Recommendations of FB invoke

The function block should be called only once per SmartCamera. Multiple calls of the function block at the same time are not allowed.

If the function block is conditionally called and the calling condition is false before FB sets it Ready output, the FB has to be initialized with the “Init” input. If the PLC restarts the “Init” input has to be set for one cycle. FB parameters can be assigned dynamically if necessary.
