Presentation
The Modicon M238 logic controller is the compact base for solutions with pre-defined
AFB, high-performance and fully expandable PLC. It forms a part of Flexible
Machine Control approach, a key component of MachineStruxure TM , which brings
you maximum flexibility and ensures the most optimised control solution.
Modicon M238 compact logic controllers offer an “all-in-one” solution in a compact
unit (157 x 118 x 86 mm excluding expansion modules).
Two models are available, with different embedded communications and supply
voltages.
bb
Model TM238 LFDC24DTS0, powered with 24 V c offers:
vv
14 x 24 V c inputs, including 8 fast inputs, dedicated to special functions such as
high-speed counting (HSC)
vv
10 x 24 V c solid state outputs, including 4 fast outputs, dedicated to special
functions such as PWM and PTO.
vv
An RS 232/RS 485 serial link (SoMachine-Network, Modbus, ASCII protocols)
vv
A CANopen bus master link
vv
A second RS 485 serial link (SoMachine-Network, Modbus, ASCII protocols)
bb
Model TM238 LFAC24DRS0, powered with 100-240 V a offers:
vv
14 x 24 V c inputs, including 8 fast inputs, dedicated to special functions such as
high-speed counting (HSC)
vv
4 x 24 V c solid state outputs, dedicated to HSC reflex functions, and 6 relay outputs
(PMW and PTO functions not supported on these models)
vv
An RS 232/RS 485 serial link (SoMachine-Network, Modbus, ASCII protocols)
vv
A CANopen bus master link
vv
A second RS 485 serial link (SoMachine-Network, Modbus, ASCII protocols).
vv
The number of I/O can be expanded on all four models by adding up to
7 expansion modules (1) of the following type on the right-hand side of the base
unit:
--
Digital TM2 DDI/DDO/DMM/DRA
--
Analog TM2 AMI/ALM/ARI/AMO/AVO/AMM
--
up to 3 High-speed counter TM200 HSC206DT/DF
Modems or communication gateways can be connected to the serial links in order to
expand the connectivity capability to include
vv
Ethernet Modbus/TCP,
vv
Profibus DP,
vv
DeviceNet,
vv
etc.
Note: A serial link on each controller delivers a 5 V c voltage dedicated primarily to powering a
Magelis display unit or Small panel terminal XBT Np00/R400/RT500 or the Ethernet gateway
499 TWD 01100.
The compact controller solution also has great flexibility in terms of wiring. With
digital I/O expansion modules, several connection options are available, including
removable screw terminals, spring terminals and HE 10 connectors, providing
simple, quick, safe wiring. The Advantys Telefast ABE 7 prewiring system can be
used for easy connection of expansion modules with HE 10 connectors.
(1) The addition of 7 expansion modules allows a maximum number per configuration of
136/192/248 I/O (depending on whether expansion modules with screw terminals, spring
terminals or HE 10 connectors are being used).
