About 20-COMM-M
The 20-COMM-M has Four (4) LED status indicators that indicates the DPI adapter communication status, and network connection. It comes with a 20-pin DPI connector that supports DPI protocol and transmission rate of 125 kbps or 500 kbps and an RJ45 connector that supports MODBUS TCP protocol and transmission rates of 10 Mbps Full Duplex 10 Mbps Half Duplex 100 Mbps Full Duplex 100 Mbps Half Duplex. It also comes with a web page switch that allows access to the adapter’s communication web page. It supports up to 30 connections or 16 simultaneous CIP messaging connections and 1 Modbus/ TCP I/O connection
The 20-COMM-M has an electrical consumption of 350 mA at 5 VDC supplied by the host (drive or DPI External Comms Kit). It must be operated at a temperature range of 10…50 °C (14…122 °F) and stored to a location with temperature of -40…85 °C (-40…185 °F) and relative humidity of 5…95% non-condensing.
The 20-COMM-M also features Ethernet connection through an RJ-45 connector and it uses the EtherNet Cable. The EtherNet Connector used is the RJ-45 type of connector it ensures a reliable data transfer is achieved. The 20-COMM-M also features a web page switch abbreviated as the SW2. This enables or disables adapter web pages. The 20-COMM-M comes with access to either of the Powerflex drives and also the connected peripherals on the network that the adapter is usually connected to. The module also features a configurable e-mail messaging feature for sending messages to the desired addresses whenever the selected drive experiences a fault. It comes with a user-defined fault action that helps in determining how the adapter and the connected drive connect to the drive. The module uses Ethernet II framing for the Modbus/TCP function protocol.

Maliha was wonderful. She got everything right the first try, formalized the quote and emailed it to me. The heavy lifting was done. I took care of ordering, address payment etc. Your website/portal was unusually easy to navigate (even by me).
Great experience from soup to nuts.

Texnite provided a power supply module which saved our NYC power plant customer from an emergency outage. We placed our order late in the afternoon. Even though it was well past their same day shipping cutoff time, Texnite still made an extra effort to ship our order immediately and the module arrived before 8am the following morning.
