3.6.1 EtherCAT configuration
“TwinCAT” from “Beckhoff Automation AG” is used for EtherCAT typical configurations. It’s also possible with other
EtherCAT master Tools.
Note:
It’s not the goal of this manual to describe the configuration of all parameters.
Operation via EtherCAT is sophisticated and requires specific knowledge and training about it and its tools.
VAT offers valve-related but not general EtherCAT support. Contact us under:

1. Data type of pressure and position values (optional)
The «data type of pressure and position» can be configured by ‘Control View’, ‘Control Performance Analyzer’ or ‘Universal
Hyper Terminal’.
The
«set-command»
is:
«s:23xxy00000»
. The xxy value is the data type of a pressure and position signal.
y: 0 = signed integer(32 bit), 1 = floating point (32 bit, IEEE-754 standard), default = 0
xx: signal number in the buffer
xx

The
«get-command»
is:
«i:23xx»
. The answer returns the data type of a pressure and position signal
«i:23xxy00000».
The y value is the current data type of buffer value xx.
Example «get-command» with Terminal: Get the data Type of Position setpoint:
Note:
If at start up the data type value in the memory is out of range the default value is taken. In this case the data type is
set to default value (0 = singed integer) and the get command i:23 add a string “False”:
