TMC4AI2

Introduction

The TMC4AI2 cartridge features 2 analog voltage or current input channels with 12-bit resolution.

The channel input types are:

0...10 V
0...20 mA
4...20 mA

For further hardware information, refer to TMC4AI2.

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.

I/O Mapping Tab

Refer to Configuring Cartridges for a description of how to configure the inputs and outputs of the module.

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	iiTMC4AI2_IWO	INT	Value of the input 0
Inputs	iiTMC4AI2_IW1	INT	Value of the input 1
Diagnostic	ibTMC4AI2_IW2	BYTE	Status of the cartridge
	Reserved	BOOL	Reserved
	Reserved	BOOL	Reserved
	24VFault	BOOL	+24 V power supply disabled
	Reserved	BOOL	Reserved
	Reserved	BOOL	Reserved
	OutOfRange0	BOOL	Input out of range (channel 0)
	OutOfRange1	BOOL	Input out of range (channel 1)
	Reserved	BOOL	Reserved

For further generic descriptions, refer to I/O Mapping Tab Description.

I/O Configuration Tab

For each input, you can define:

Parameter		Value	Default Value	Description
Type		Not used 0 - 10 V 0 - 20 mA 4 - 20 mA	Not used	Select the mode of the channel.
Min.	0 - 10 V	-32768...32767	0	Specifies the lower measurement limit.
	0 - 20 mA		0
	4 - 20 mA		4000
Max.	0 - 10 V	-32768...32767	10000	Specifies the upper measurement limit.
	0 - 20 mA		20000
	4 - 20 mA		20000
Filter Level		No Filter Filter1 (Shortest) ... Filter6 (Longest)	No Filter	Specifies the digital filtering level to apply on this channel.
