

The designer of any control scheme must consider the potential failure modes of control paths
and, for certain critical control functions, provide a means to achieve a safe state during and
after a path failure. Examples of critical control functions are emergency stop and overtravel
stop, power outage and restart.
Separate or redundant control paths must be provided for critical control functions.
System control paths may include communication links. Consideration must be given to the
implications of unanticipated transmission delays or failures of the link.
Observe all accident prevention regulations and local safety guidelines.1
Each implementation of this equipment must be individually and thoroughly tested for proper
operation before being placed into service.
Failure to follow these instructions can result in death, serious injury, or equipment
damage.

I/O Configuration General Information
TM7 Expansion Modules General Description
Introduction
The range of expansion I/O includes:
TM7 Digital I/O blocks
 TM7 Analog I/O blocks
 TM7 Power Distribution Blocks

Digital or analog input blocks convert measured values (voltages, currents) into numerical values
which can be processed by the controller.
Digital or analog output blocks convert controller internal numerical values into voltages or
currents.
Analog temperature blocks convert the temperature measurement values into number values
which can be processed by the controller. For temperature measurements, the temperature block
returns the measured value using 0.1 °C (0.18 °F) steps.
The Power Distribution Blocks PDB are used to manage the power supply for the various I/O
blocks. The PDB feeds the TM7 power bus.
NOTE: The TM7 I/O blocks are associated with power cables, TM7 bus cables and I/O cables.

I/O Configuration General Information
Match Software and Hardware Configuration
The I/O that may be embedded in your controller is independent of the I/O that you may have
added in the form of I/O expansion. It is important that the logical I/O configuration within your
program matches the physical I/O configuration of your installation. If you add or remove any
physical I/O to or from the I/O expansion bus, update your application configuration (this is also
true for any field bus devices you may have in your installation). Otherwise, there is the potential
that the expansion bus or field bus will no longer function while the embedded I/O that may be
present in your controller will continue to operate.
WARNING
UNINTENDED EQUIPMENT OPERATION
Update the configuration of your program each time you add or delete any type of I/O expansions
on your I/O bus, or you add or delete any devices on your field bus.
Failure to follow these instructions can result in death, serious injury, or equipment
damage.
To verify if the hardware and software configuration match, use the GVL TM5_Module_R function
to monitor the expansion bus status.
Adding a TM7 Expansion Module
To add a TM7 expansion module, refer to the Modicon TM7 Expansion Blocks Configuration
Programming Guide (see page 18).

I/O Configuration General Information
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:
Be longer than the greatest Minimum Cycle Time of any expansion module or block in the
configuration.
 Be 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 (see Modicon TM5, Expansion Modules Configuration,
Programming Guide) tab of each module. 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 (see Modicon
TM5 / TM7 Flexible System, System Planning and Installation Guide).

Filter Level
The input value is evaluated according to the filter level. An input limitation can then be applied
using this evaluation.
Formula for the evaluation of the input value:
The following examples show the function of the input limitation based on an input jump and a
disturbance.
Example 1: The input value makes a jump from 8000 to 16000. The diagram displays the

Input Limitation
Input limitation can only take place when a filter is used. Input limitation is executed before filtering
takes place.
The amount of the change in the input value is verified to make sure the specified limits are not
exceeded. If the values are exceeded, the adjusted input value is equal to the old value ± the limit
value.
The input limitation is well suited for suppressing disturbances (spikes). The following examples
show the function of the input limitation based on an input jump and a disturbance.
Example 1: The input value makes a jump from 8000 to 17000. The diagram displays the adjusted

Raw Value Measurement
If a sensor type other than J, K or S is used, the terminal temperature must be measured on at least
one input. Based on this value, the user must perform a terminal temperature compensation.
Terminal Temperature (Cold Junction) Compensation
When using thermocouples, it is necessary to measure the temperature at the terminal
connections of the TM7BAI4PLA in order to calculate an accurate absolute temperature at the
measuring point of the thermocouple. The sensor used to measure the terminal temperature is
integrated in the TM7ACTHA thermocouple connector.
NOTE: At least one terminal temperature sensor TM7ACTHA (see Modicon TM7, Analog I/O
Blocks, Hardware Guide) is required to determine the temperature measured by the connected
thermocouples. Otherwise, a value of 7FFF hex is calculated for all the connected thermocouples.
The accuracy of the temperature measurement of the connected thermocouples is a function of
the number of terminal temperature sensors connected to the block.
NOTE: If the J, K and S types are used, you must select the terminal temperature compensation.
The temperature measured at the external reference junction is stored in the I/O area of the
TM7BAI4PLA block. The TM7BAI4PLA block calculates the thermocouple temperature internally
from the measured voltage and the reference junction temperature value (per channel).

Input Limitation
Input limitation can only take place when a filter is used. Input limitation is executed before filtering
takes place.
The amount of the change in the input value is checked to make sure the specified limits are not
exceeded. If the values are exceeded, the adjusted input value is equal to the old value ± the limit
value.
The input limitation is well suited for suppressing disturbances (spikes). The following examples
show the function of the input limitation based on an input jump and a disturbance.
