Goals and Symptoms
cae we connect HMI device to ATV31. we are trying to use a magelis screen to communicate direct with ATV31 viA the RJ45 terminal. we are currently using the smae cable we use to communicate with ATV28, Tesys U devices. We are unable to to communicate with the drive. is this possible, do we need a special cabel ( different pin outs) or we can not do this.
Causes and Fixes
There is no problem to connevt ATV31 on a Magelis, it's the same pinout on the RJ45 like the ATV28 or Tesys U, but there is no pull up / pull down on the ATV31. Be careful because the factory setting baudrate is not the same on ATV31, it's 8e1 and ATV28 is 8n1. Verify also if the two small dip switch near the RJ45 connector are in up position.
