TM5 / TM7 Controller System Architecture
The TM5 / TM7 System is a flexible control system. The following graphic depicts a typical architecture with an LMC058 motion controller:
The flexibility is obtained by the association of:
oTM5 System
oTransmitter / Receiver modules
oField bus interface module
oCompact I/O
oSlices
oAccessories
oTM7 System
oTM7 Field bus interface I/O blocks
oBlocks
oAccessories
The controller with embedded I/Os and networking is the main component of the TM5 / TM7 System. It can be expanded by compact I/O, slices and/or blocks.
An expansion module is a compact I/O or a slice in this documentation.
The compact I/O is used to expand and adjust the number of I/O in the TM5 System to the exact needs of your application.
A slice has one of the following functions in the TM5 System:
oExpansion I/Os or
oPower distribution or
oCommon distribution or
A block has one of the following functions in the TM7 System:
oExpansion I/Os or
oPower distribution
The expansion modules and blocks are used:
oto expand and adjust the number of I/O in a TM5 / TM7 System to the exact needs of your application.
oto manage the distribution of power for electronic modules and I/O (for example separation of 24 Vdc inputs from 24 Vdc outputs...)
Application requirements determine the architecture of your TM5 / TM7 System.
Depending on your needs, the local configuration architecture may optionally be expanded to include remote expansion I/Os and/or distributed I/O systems.
Remote I/O expansions are made by extending the internal TM5 data bus through the use of TM5 Transmitters and Receivers.
Distributed I/O expansions are made through the use of industrial networks (such as CANopen, Ethernet,...). These networks can be created using the integrated communication ports on the controller or the optional TM5 PCI modules.
Local Configuration Architecture
The local configuration architecture is composed of the controller and its embedded power distribution and I/O modules, as well as any installed PCI and local expansion I/O modules.
NOTE: A local configuration is only possible with the TM5 system.
The following figure represents a controller with expansion I/Os on a local TM5 bus:
1 Controller
2 Embedded I/Os
3 Local expansion I/Os
NOTE: Embedded I/Os cannot be separated from the controller.
Remote Configuration Architecture
In addition to your local configuration you can place remote I/Os at a distance up to 100 m (328.1 ft) from the controller.
NOTE: You can create remote I/Os with TM5 expansion modules and/or TM7 expansion blocks.
Refer to Modicon TM5 Transmitter and Receiver Modules Hardware Guide to design remote configurations.
