2.1.2.3. CONFIGPPORT message

This command is valid only for E401.

This is the message sent by the controller to change the available inputs/outputs configuration. This

configuration will be saved.

Address: CC  E401

Syntax: Command:

CONFIGPPORT

Parameters:

Address list (I: input, O: output, X: not used)

Initial value list (1, 0, X: not used / input)

Example: CONFIGPPORT OIIOOOXXXXXXXXXXXX/0XX000XXXXXXXXXXXX&

In the example we are using 6 out of the 18 available inputs/outputs, 4 of them are configured as

outputs (address “O”) with a low level initial status (value “0”) and the 2 balanced are configured as

inputs (address “I”, value “X”).

For the rest of inputs/outputs remaining unused, the parameters command, address and initial value

are filled in with “X”.

E401 changes the inputs/outputs initial configuration and sends the message ACK_CONFIGPPORT

back.

2.1.2.4. ACK_ CONFIGPPORT message

This command is genereted only by E401.

This is the message that E401 has to send when answering to CONFIGPPORT.

Address: E401  CC

Syntax: Command

ACK_CONFIGPPORT

Parameters: None

2.1.2.5. WRITEPPORT message

This is the message that the controller sends to the controller to write remotely over the output-

configured pins in the case of E401.

Regarding E451, with this command we can write over the relay output contact.

Address: CC  E400

Syntax: Command

WRITEPPORT

Parameters: List of the desired value (1, 0, X: not used / input)

Exemple: [E401]: WRITEPPORT 0XX110XXXXXXXXXXXX&

[E451]: WRITEPPORT X1&

The pins configured as inputs must not be affected by this message. Therefore, as parameter we will

use the value “X” for them and for the unused pins.

In the case of E451 the parameter of this command will have only two characters. The first one will

always be “X” since it is an input, and the second one can be either “1” or “0”depending on what we

want to write in the output.

E400 writes in the pins and answers with the message ACK_WRITEPPORT.
