Access the IOs from the command line or via script
application
This chapter provides information about query and control of the digital and analog inputs
and outputs of an EWIO
2
from the command line or per scripts application.
For this purpose, a command line tool named „ewioIOControl“ is installed on the EWIO
2
.
This tool can be used to send a single command to the ewio2Server, the central software
control unit, in order to query or control an I/O pin at a time.
11.1.
Calling conventions
The general syntax of the CLI Tool is:
ewioIOControl <command>
where <command> has the following structure:
<base_command>_<io-category>_<module-addr>_<pin-addr>[_value]
The <base-command> possible values are „set“ or „get“.
The <io-category> may be one of „ai“, „ao“, „di“, „do“, „aisensor“ or „dicount“
Each individual pin (digital or analog In-/Output) is identified by it’s address.
The address consists of two parts: module address and pin address.
The module address
<module-addr>
ever has the value 0 for the EWIO
2
base device and the
values 1-6 for the extention modules.
The
<pin-addr>
is the address of the pin of a certain category for a module at address
<module-addr>. The pin address must be entered with two digits with leading zeroes and
begins always with „00“.
The [_value] part is optional (only for “set” commands) and represents the value to be set (for
digital outputs 0 or 1, for analog outputs the float value with decimal point, for ai the sensor
id : integer according definition table, di counter : positive integer value).
More detailed, the <command> parameter looks like:
set|get_ai|ao|di|do|aisensor|dicount _<moduladdr>_<pinaddr>[_value]
