M Measurement I Input
R Relay function A Analogue output (current)
Measurement :
De measurement value will be stored.
When the unity and number of decimals are predefined then this will be shown in this table. When this
is programmable then this can vary and the unity and number of decimals can be read in the
corresponding registers (see § 21.1.2 “Register : unities / decimals” at page. 89).
Digital inputs :
De state of the digital input function will be read bit wise :
0x8000 Function not linked to hardware in the inventory
0x4000 Function activated
0x2000 Function activated, but within delay time
0x1000 Function activated, delay time passed
0 Function not active
Relay outputs :
De state of the relay output function will be read bit wise :
When a security switch is defined then the state of this switch will also be indicated bit wise. When a
analog output is defined the value (in %) will be indicated in the LSB byte.
0x8000 Function not linked to hardware in the inventory
0x4000 Relay active position
0x1000 Function activated
0x0400 Security switch activated
0x0200 Security switch activated but within delay time
0x0100 Security switch activated, delay time passed
0x00aa aa = The value of the analogue output will be shown in 1%. This is the
percentage between the minimal and maximal current (0-20 or 4-20mA).
Analogue outputs :
The value of the analogue output will be shown in 1%. This is the percentage between the minimal
and maximal current (0-20 or 4-20mA).
