Schneider Electric TM262L10MESE8T Modicon M262 Controller

TM262L10MESE8T: Modicon M262 logic/motion controller, 5 ns class

The TM262L10MESE8T is a Modicon M262 logic and motion controller from Schneider Electric, aimed at machines that must connect to the cloud and to the plant. It has eight built-in fast I/O points, two Ethernet interfaces, a serial line and a TM3 expansion bus, and it executes 1 K instructions in 0.005 ms.

In the M262 pair on this site, TM262L10MESE8T is the 5 ns member and TM262L20MESE8T is the faster 3 ns version. The datasheet describes the family as IIoT-ready, with a machine-to-cloud and machine-to-plant orientation. Seven Star LLC supplies the this unit in Oman and the GCC as an independent supplier based in Muscat.

Selection checklist and RFQ details for the TM262L10MESE8T

Check before ordering:

• whether the instruction time of 0.005 ms is adequate or the 0.003 ms TM262L20MESE8T is justified
• the number of EtherNet/IP and Modbus TCP devices to be scanned, against the limit of 96
• whether the project needs encrypted OPC UA server only, since the client option is on the faster unit
• the expansion modules required
• cabinet orientation and temperature

Send quantity, delivery location and the programming software version used for the project.

Expansion options for the TM262L10MESE8T

Up to seven TM3 I/O modules can be fitted on the controller itself, in either the local or remote architecture. For larger systems the datasheet lists up to 64 TM3, TM5 or TM7 modules in distributed I/O islands.

This gives more headroom than the M221 and M241 controllers, which suits plants where later expansion is likely. The TM3 modules named in the same range, such as TM3DI16G, TM3DQ16RG or TM3TI4G, are compatible with the M262 according to their own datasheets.

Memory and speed of the TM262L10MESE8T

Program RAM is 32 MB, OS and website RAM is 32 MB and system RAM is 192 MB, with 1 GB of built-in flash for backing up the user program and an optional SDHC card up to 32 GB. The cycle time is 0.5 ms, and tasks include eight event tasks, four cyclic master tasks (or three plus a freewheeling task) and eight external event tasks.

The real-time clock drifts by no more than 10 s per month at 25 °C and the backup time is 1000 hours at 25 °C.

Installation of the TM262L10MESE8T in Gulf environments

The housing measures 125 × 100 × 90 mm and weighs 0.655 kg, with fixing on a 35 mm DIN rail or a panel using the kit. Operation is rated from −20 to 60 °C when horizontal, −20 to 50 °C vertical and −20 to 45 °C flat-mounted, and storage from −40 to 85 °C. Humidity is 10 to 95 % without condensation and the case is IP20.

Gulf cabinets get hot: use the vertical or flat ratings, not the horizontal one, if the panel orientation is not horizontal. Spring terminal blocks carry the I/O and the 24 V supply, and the supply inrush current is 40 A.

Fast I/O and motion on the TM262L10MESE8T

The four fast inputs respond in 1 µs or less, with filter times selectable from 0.001 ms to 12 ms. The four fast outputs are source transistors rated 0.5 A at 24 V DC and can toggle up to 300 kHz, again with response of 1 µs or less. Short-circuit, overload and reverse-polarity protection are listed, with a 200 ms automatic reset on a fast output.

For positioning, the datasheet refers to a library of coordinated-axes functions. Heavier motion tasks that need more axes are normally served with drives on a fieldbus or on the distributed I/O.

Communication and security services of the TM262L10MESE8T

The M262 has one Ethernet RJ45 port for 10/100 Mbit/s and a second Ethernet connection made of two RJ45 sockets that work as a 10/100/1000 Mbit/s switch, which the datasheet pairs with Ethernet RSTP. It also has an RJ45 serial line (RS232/RS485), a mini-B USB port, the Smart Communication Bus and the TM3 I/O bus.

Protocols listed include EtherNet/IP adapter and scanner, Modbus TCP client/server and I/O scanner, Modbus serial client/server, MQTTs, OPC UA server with encryption, HTTPS methods, a web server and WebVisu, TLS 1.2 and 1.3, SNTP and NTP, FTP and FTPs, SQL client, DHCP, DNS, SMTP, POP3s and SNMP. Combined connection capacity is 96 Modbus TCP and EtherNet/IP devices, with up to 64 devices of each type.
