III-10 Communication
ISO 1745
In total, max. 20 L1READ and L1WRIT functions can be configured (blocks 1...20 ), any combination of functions is pos -
sible. Any number of data can be used in the functions.
III-10.1 L1READ ( read level1 data(No. 100) )
General
Any 7 analog process values (x1...x7) and any 12 digital status informations (d1...d12) of the engineering are composed into a
data set for the digital interface. The digital interface can read the data set as a complete block with code 00, function num-
ber 0, or the individual values with codes 01...09, function number 0.
Inputs/outputs
Digital inputs:
d1 ... d6
Digital process values, which can be read via interface (status byte 1). (Default = 0)
d7 ... d12 Digital process values, which can be read via interface (status byte 2). (Default = 0)
Analog inputs:
x1 ... x7
Analog process values, which can be read via interface. (Default = 0)
Engineering example
In the following example, several process data (process value, effective and control deviation) and controller statuses
(automatic/manual, Wint/Wext and y/Y2) are connected with the L1READ function block. Now, these data can be read
in a message via interface.
