TM5 Manager Configuration

To configure the TM5 Manager, proceed as follows:

Step	Action
1	In the Devices tree, expand the TM5 node.
2	Double-click the TM5_Manager node. Result: The TM5 Manager configuration window is displayed.
3	Select the I/O Configuration tab.

Step

Action

In the Devices tree, expand the TM5 node.

Double-click the TM5_Manager node.

Result: The TM5 Manager configuration window is displayed.

Select the I/O Configuration tab.

Parameters of the I/O Configuration:

Parameter	Value	Default Value	Unit	Description
Bus Cycle Time	0.5 ms 1 ms 2 ms 3 ms 4 ms 5 ms	1 ms	ms	Expansion Bus Cycle Time
Maximum number of physical slots	Number of Embedded modules...250	250	-	Maximum number of modules on the expansion bus.
Name of FW repository	Not configurable	-	-	This parameter indicates the Flash memory repository for the modules firmware.
Maximum bus length in meters (feet)	1...2500 (3.28...8202)	100 (328)	m	Total cable length used on the expansion bus.

NOTE: For more information about the maximum capacities of your system, refer to the TM5 / TM7 System Planning and Installation Guide.

Bus Cycle Time

Bus Cycle Time can be configured from 0.5 to 5 ms. Very fast cycles reduce the idle time for handling monitoring, diagnostics and acyclic commands.

The Bus Cycle Time follows 2 rules:

oBe longer than the greatest Minimum Cycle Time of any expansion module or block in the configuration.

oBe long enough to permit the data exchange with all the modules and the blocks.

Minimum Cycle Time

The Minimum Cycle Time of a module or of a block is the time needed by the module or the block to perform I/O management. If the Bus Cycle Time is shorter than this minimum value, the module will not operate properly.

Minimum I/O Update Time

The Minimum I/O Update Time of a module or block is the time needed by the module or block to update I/O on the bus. If the Bus Cycle Time is shorter than this minimum value, the I/O will be updated on the bus at the next Bus Cycle Time.

I/O Management

At the beginning of each task, the %I memory variable for the inputs used in the task is updated with the physical state of the input.

At the end of each task, the used %Q memory variable value for the outputs is updated.

On the next bus cycle after the end of the task configured as the Bus cycle task, the physical output is updated from the %Q memory variable value.

For more details on Bus cycle task, refer to the controller PLC settings tab.

Power Consumption

To display the estimated power consumption of the expansion modules:

Step	Action
1	Right-click the TM5_Manager node of the Device tree.
2	Select Power consumption.

NOTE: The current consumption figures presented by the Power consumption function are based on assumed values, and not on actual current measurements. The assumed values for the outputs are based on classic loads but can be adjusted using the 24 Vdc I/O segment external current setting in the I/O Configuration tab of each module (refer to the Modicon TM5 Expansion Modules Configuration Programming Guide). The assumptions for input signals are based on known internal loads and are therefore not modifiable. While the use of the Power consumption function to test the power budget is required, it is no substitute for actual and complete system testing and commissioning. Refer to the TM5 TM7 System Planning and Installation Guide.
