5.12 DB, data block
The function block stores values such as setpoints for function blocks.
The value applied to input I1 is saved in the operand linked to output QV.
easy800 device allows the use of up to 32 data function blocks.
Contacts and Coils
Example of a data function block
Figure 127:Wiring the trigger coil
The trigger coil is addressed via the network.
Figure 128:Wiring of the function block contact
The output of the data function block DB16Q1 is assigned to the input
D02 EN of the text display function block.
Parametric programming of the function block inputs/outputs
When using the function block in the circuit diagram for the first time, use
OK to automatically enter the general display of function block parameters,
as shown in the figure on the left. Enter the function block settings here.
The display contains the following elements:
Input
I1: You apply the value that is transferred on triggering to the function block
input I1. The function block input I1 can be assigned the following operands:
•
Constant.
•
Markers MD, MW, MB.
•
Analog inputs IA01 to IA04:
•
IA01: Terminal I7.
•
IA02: Terminal I8.
•
IA03: Terminal I11.
•
IA04: Terminal I12.
