Ethernet Communication and I/O Processing

The TM241CE24T combines 24 integrated I/O points with Ethernet, serial communication, and high-speed I/O functions. Its 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 an OPC UA server, web server functions, FTP, SNMP, DHCP, firmware updating, and SQL client functions.

The eight fast inputs support high-speed counting and pulse processing, including A/B, pulse/direction, and single-phase signals. Four fast outputs provide PTO, PWM, and PLS functions, with PLS operation specified up to 100 kHz.

The integrated memory consists of 8 MB program memory, 64 MB system RAM, and 128 MB built-in flash for user-program backup. An optional SD card supports storage up to 16 GB.

Frequently Asked Questions

Q: What supply voltage does the TM241CE24T require?
A: The rated supply voltage is 24 VDC, with an allowed supply range of 20.4 to 28.8 VDC.
Q: What are the maximum fast I/O frequencies?
A: The four fast inputs support up to 200 kHz in HSC mode. Fast outputs support up to 100 kHz in PLS mode and 20 kHz in PWM mode.

Q: Does the controller provide galvanic isolation between all I/O channels?
A: No. The source specifies 500 VAC insulation between several I/O groups and internal logic, while inputs and outputs are specified as non-insulated between channels o
