The E5ER / E5AR Temperature Controllers all use Compoway-F communica-
tions over 2-wire RS-485.
• The RS-485 connection can be either one-to-one or one-to-N. Up to 15
Temperature Controller units can be connected in a one-to-N system.
• The total cable length is 500 m max.
The figure below shows the connection between one PROFIBUS-DP Gate-
