Connecting Temperature Controllers Section 1-3
Controllers can be connected in any order. The unit number of each Tempera-
ture Controller is set using the upper rotary switch on the front panel of the
Temperature Controller. Always set a unique unit number for each Tempera-
ture Controller.
Up to 16 Temperature Controllers can be connected to a single DeviceNet
Communications Unit. RS-485 connections also support up to 16 Tempera-
ture Controllers.
The E5ZN-SDL Setting Display Unit for E5ZN Temperature Controllers can be
connected at the same time.
Note There is no priority between operation commands and settings for DeviceNet
communications from the master or Configurator, and operation commands
and settings from the Setting Display Unit. Do not change the same data or
send different operation commands more than one source at the same time.
1-3-2 Temperature Controller Communications
The DeviceNet Communications Unit and Temperature Controllers communi-
cate at a baud rate of 38,400 bps. Set the baud rate using the lower rotary
switch on the front panel of the Temperature Controllers to 3 (= 38,400 bps).
Communications are performed using a transmission format of 7-bit data, 2
stop bits, and 2 parity bits. These are the default settings. If the default values
have been changed, use the E5ZN-SDL Setting Display Unit to return the
Temperature Controller settings to 7-bit data, 2 stop bits, 2 parity bits.
1-3-3 Temperature Controller Models
The DeviceNet Communications Unit can be connected to the following Tem-
perature Controllers.
1-3-4 Temperature Controller Power Supply
Power is supplied to the Temperature Controllers through terminals 19 and 20
of the E5ZN-SCT24S Terminal Units.
