The DMX512 is a protocol data transmission that uses the EIA RS485 international standard. The protocol uses a two-conductor cable (twisted pair) to connecting up to 512 devices up to a distance of 500m. A control frame for all 512 devices takes about 23 ms to be sent. This corresponds to a refresh rate of about 44 Hz, if you need a higher refresh rate can be control less devices.

The DMX protocol is used to control theathers scenarios and lighting effects. There is a wide market availability of spotlights, scenic machineries, dimmers, etc. provided with DMX interface. By being able to drive all these devices through a single serial connection it's evident how to handle scenarios according to proper needs.

Our DMX protocol offer is focused on the availability of a function block FbDMXProtocol that used on our Picosyst or Netsyst serie products allows to manage the protocol. So it's possible to turn on/off lights, adjust the brightness, change the orientation and color directly from the device. It's possible create scenarios that can be activated by the activation of simple logic inputs, avoiding the use of more expensive command units.

Even for the new SlimLine family, the SysDMXMng function block, for the DMX management has been released. This to manage the protocol within a programming environment typical of PLC according to IEC-61131-3
