ACO020: Configuring the Quantum module ACO 020 00

Original instructions

Function description

The function block is used to edit the configuration data of an ACO 020 00 Quantum module for subsequent use by the scaling EFBs.

This module has 4 output channels for the processing of current in the range of 4...20 mA.

For the configuration of an ACO 020 00 the function block in the configuration section is connected to the corresponding SLOT output of the QUANTUM or DROP function block. The specified in the I/O map and the status information (if configured) are automatically assigned internally to the individual channels and can therefore only be occupied by Unlocated variables.

The analog values can be further processed in Scaling sections using the O_NORM, O_NORM_WARN, O_RAW, O_SCALE, and O_SCALE_WARN procedures.

and can be configured as additional parameters.

Parameter description

Parameter	Data type	Meaning
SLOT	INT	Module slot

Description of output parameters:

Parameter	Data type	Meaning
CHANNEL1	ANL IN	Channel 1
CHANNEL2	ANL_OUT	Channel 2
CHANNEL3	ANL_OUT	Channel 3

Runtime error

If no ACO 020 00 module has been configured for the specified SLOT input, an error message is returned.

The status information "Open circuit on channel" can be requested via the status register defined in the I/O map.

NOTE: For a list of all block error codes and values, seeQuantum I/O Configuration.

%MW

According to the CEI standard, %MW indicates a language object of type memory word.

EN stands for ENable; it is an optional block input. When the EN input is enabled, an ENO output is set automatically.

If EN = 0, the block is not enabled; its internal program is not executed, and ENO is set to 0.

If EN = 1, the block's internal program is run and ENO is set to 1. If an error occurs, ENO is set to 0.

If the EN input is not connected, it is set automatically to 1.

ENO

ENO stands for Error NOtification; this is the output associated with the optional input EN.

If ENO is set to 0 (because EN = 0 or in case of an execution error):

the status of the function block outputs remains the same as it was during the previous scanning cycle that executed correctly;
the output(s) of the function, as well as the procedures, are set to "0".

INT

INT is the abbreviation of single INTeger (encoded in 16 bits).

The upper/lower limits are as follows: -(2 to the power of 15) to (2 to the power of 15) - 1.

Example:

-32768, 32767, 2#1111110001001001, 16#9FA4.

ANL_IN

ANL_IN is an internal data type that is used between Quantum specific FFBs. For instance, an ACI040 FFB provides the channels structures of the module as ANL_IN types, which are used as input of an I_FILTER FFB. This data type must not be used outside the Quantum specific FFBs.
