TM7BAI4TLA

Introduction

The TM7BAI4TLA expansion block is a 4 channel Analog Resistor Temperature input block with input sensor type PT and KTY or resistor.

For further information, refer to TM7BAI4TLA Block 4AI PT100/PT1000.

TM7 Module I/O Mapping Tab

Variables can be defined and named in the TM7 Module I/O Mapping tab. Additional information such as topological addressing is also provided in this tab.

This table describes the I/O Mapping configuration:

Variable	Channel	Type	Description
–	ModuleOK	BYTE	State of the compact I/O and electronic modules
–	DiagIn	BYTE	Status bit associated to each input: o0: OK o1: Error detected
Inputs	RTD input 1	INT	Current value of the input 0
	RTD input 2		Current value of the input 1
	RTD input 3		Current value of the input 2
	RTD input 4		Current value of the input 3

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

Analog Inputs

Different resistance or temperature measurements result in different value ranges and data types.

Sensor Type and Channel Deactivation

The block is designed for temperature and resistance measurement. The sensor type must be specified because of the different adjustment values for temperature and resistance. To save time, individual channels can be switched off.

This table shows the sensor types:

Sensor Types	Digital Value	Temperature °C (°F)	Resolution °C (°F)
Sensor type PT100	-2000...8500	-200...850 (-328...1562)	0.1 (0.18)
Sensor type PT1000	-2000...8500	-200...850 (-328...1562)	0.1 (0.18)
Sensor type KTY10-6	500...1450	-50...145 (48...293)	0.1 (0.18)
Sensor type KTY84-130	400...3000	-40...300 (40...572)	0.1 (0.18)
Resistance measurement 0.1...4500 Ohm	1...45000	–	0.1 Ohm
Resistance measurement 0.05...2250 Ohm	1...45000	–	0.05 Ohm

User-Defined Parameters Tab

The table describes the user-defined parameters of the module:

Parameter	Value	Default Value	Description
