TM3AI2H / TM3AI2HG

Introduction

The TM3AI2H (screw terminal block) / TM3AI2HG (spring terminal block) expansion module features 2 analog input channels with 16-bit resolution.

The channel input types are:

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

For information on the diagnostic codes produced by each input type, refer to Analog I/0 Modules Diagnostics.

For further hardware information, refer to TM3AI2H / TM3AI2HG.

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 input, 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	0	Specifies the lower measurement limit.
	-10 - +10 V		-10000
	0 - 20 mA		0
	4 - 20 mA		4000
Max.	0 - 10 V	-32768...32767	10000	Specifies the upper measurement limit.
	-10 - +10 V		10000
	0 - 20 mA		20000
	4 - 20 mA		20000
Input Filter		0...1000	0	Specifies the first order filter time constant (0...10 s) in increments of 10 ms.
Sampling		1ms/Channel	1ms/Channel	Specifies the sampling period of the channel.
Status Enabled		Yes No	Yes	Enables the diagnostic byte of each channel. If the status is disabled (value = No), the status bytes `IBStatusIW0` and `IBStatusIW1` do not contain relevant information.

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	Description
Inputs	IW0	INT	Current value of the input 0
Inputs	IW1	INT	Current value of the input 1
Diagnostic	IBStatusIW0	BYTE	Status of input 0
Diagnostic	IBStatusIW1	BYTE	Status of input 1
