Low-Level Drivers FB15 and FB16

FB15 contains respective copy operations to write structured commands and data into the process image. Plain text 
information is in the input area:

•  Command
•  Channel
•  Transaction Number (TAN)
•  Lines
•  Value Code
•  Value as REAL value
•  Value as INT value

The input area also includes various flags: Busy, Handshake, Local Service, Error, and Selection Switch (for 
choosing either integer or floating decimal point).
The function block compiles the individual bytes of the process image from this information. The input information 
is copied to the proper address in the process image. Copying occurs with each call. A CAN message to the PICO 
controller is only sent if a bit is changed in the process image. Thus, a cyclic call (e.g., in OB1) may occur. By using 
various transaction numbers, the same configuration command can be sent repeatedly.
The ability to the select the data format is also included in the range of functions of FB15. One of the two input 
formats available for selection (REAL value/INT value) will be copied into the process image via a selection switch. 
Therefore, it is possible to implement a uniform format (REAL) for all configuration data in higher protocol levels.
The outputs of FB15 (CAN_Byte0 to CAN_Byte7) must be connected with the respective address in the PABx 
process image.
FB16 contains the respective complimentary copy operations needed to convert the process image to structured 
data. The addresses containing the received CAN data are provided in the input area of the function block.
FB16 copies the process image into structured information. The respective receiving addresses PEBx in the process 
image must be provided.
The following information is deposited in the output area with each call of the function block:

•  Command
•  Channel
•  Transaction number (TAN)
•  Line
•  Value Code
•  The value interpreted as an integer value
•  The value interpreted as a floating decimal point value
•  Various flags (Busy, Handshake, Local Service, Error)

If multiple PICO controllers will be controlled by one PLC, the respectively differing process image address ranges 
must be issued for each individual PICO controller and multiple instances of FB15/FB16 must be used.
