TM3AQ2 / TM3AQ2G

Introduction

The TM3AQ2 (screw terminal block) / TM3AQ2G (spring terminal block) expansion module features 2 analog output channels with 12-bit resolution.

The channel output types are:

0...10 V
-10...+10 V
0...20 mA
4...20 mA

For further hardware information, refer to TM3AQ2 / TM3AQ2G.

NOTE:

If you have physically wired the analog channel for a voltage signal and you configure the channel for a current signal in EcoStruxure Machine Expert, you may damage the analog circuit.

NOTICE
	INOPERABLE EQUIPMENT Verify that the physical wiring of the analog circuit is compatible with the software configuration for the analog channel. Failure to follow these instructions can result in equipment damage.

Configuring the Module

For each output, you can define:

Parameter		Value	Default Value	Description
Type		Not used 0 - 10 V -10 - +10 V 0 - 20 mA 4 - 20 mA	Not used	Choose the mode of the channel.
Min.	0 - 10 V	-32768...32767⁽¹⁾	0	Specifies the lower measurement limit.
	-10 - +10 V		-10000
	0 - 20 mA		0
	4 - 20 mA		4000
Max.	0 - 10 V	-32768...32767⁽¹⁾	10000	Specifies the upper measurement limit.
	-10 - +10 V		10000
	0 - 20 mA		20000
	4 - 20 mA		20000
Status Enabled		Yes No	Yes	Enables the diagnostic byte of each channel. If the status is disabled (value = No), the status bytes `IBStatusQWx` do not contain relevant information.
⁽¹⁾ The 12-bit data (0 to 4095) processed in the analog I/O module can be linear-converted to a value between -32768 and 32767.

I/O Mapping Tab

Variables can be defined and named in the I/O Mapping tab. Additional information such as topological addressing is also provided in this tab.

This table describes the I/O Mapping tab:

Variable	Channel	Type	Default Value	Description
Outputs	QW0	INT	-32768...32767	Command word of the output 0
Outputs	QW1	INT	-32768...32767	Command word of the output 1
Diagnostic	IBStatusQW0	BYTE	-	Status of output 0
Diagnostic	IBStatusQW1	BYTE	-	Status of output 1
