Ethernet, I/O Density and Firmware Functions

The TM241CE40T combines 40 integrated discrete I/O points with Ethernet and serial communication interfaces. The 24 inputs include 8 fast inputs supporting high-speed counting functions up to 200 kHz. Four transistor outputs provide fast output functions, with PWM operation up to 20 kHz and PLS operation up to 100 kHz.

The Ethernet interface operates at 10/100 Mbit/s and supports Modbus TCP client/server functions and EtherNet/IP scanner and target functions. The controller also provides firmware updating through its Ethernet service set. Application memory consists of 8 MB program memory, 64 MB system RAM, and 128 MB built-in flash for user-program backup.

The controller supports EcoStruxure Machine Expert for application programming. Its integrated Ethernet services include DHCP, SNMP, FTP, web server, OPC UA server, SQL client, and Modbus TCP and EtherNet/IP communication functions.

Frequently Asked Questions

Q: What supply voltage does the TM241CE40T require?
A: The controller is rated for 24 VDC, with a specified supply range of 20.4-28.8 VDC.

Q: Are the integrated Ethernet and serial interfaces electrically isolated?
A: The Ethernet interface is provided through an RJ45 connection. Both integrated serial links are specified as non-isolated.

Q: What are the fast I/O limits?
A: Eight fast inputs support HSC operation up to 200 kHz. Four fast transistor outputs support PWM up to 20 kHz and PLS up to 100 kHz.

Field Installation Guidelines

• Mount the controller on a TH35-15 or TH35-7.5 DIN rail according to IEC 60715, or use the specified plate or panel mounting method.
• Supply the controller within the specified 20.4-28.8 VDC range and observe the 50 A stated inrush current when sizing the power supply and protective devices.
• Use the removable screw terminal blocks for 24 VDC power and discrete I/O connections. The specified terminal pitch is 5.08 mm.
• Keep input and output wiring within the specified cable-distance limits. Standard input and output wiring is specified up to 50 m with unshielded cable.
• For fast signals, observe the shorter specified limits: shielded fast-input wiring is limited to 10 m and shielded fast-output wiring to 3 m.
• Route fast I/O and communication cables separately from high-current or high-noise conductors where practical to reduce electrical interference.
• Connect cable shields according to the machine grounding design and applicable EMC requirements. Avoid creating unintended ground loops through multiple shield termination paths.
• Maintain the specified environmental limits of -10 to 50 deg C for vertical installation or -10 to 55 deg C for horizontal installation, with non-condensing humidity.
• Keep the controller within its IP20 installation environment and use the protective cover where specified.
• For Ethernet commissioning, verify the assigned IP configuration and communication parameters before enabling Modbus TCP or EtherNet/IP data exchange.
• When using high-speed inputs or outputs, verify signal wiring, polarity, load characteristics, and configured frequency before applying the machine power stage.
