WATLOW®EZ-ZONE®RMZ4 - 5- ETHERCAT® ADAPTER
3OVERVIEW
The Watlow EtherCAT® Adapter allows integration of the EZ-ZONE RM systems into larger EtherCAT®
controlled processes. EtherCAT® is an industrial control network that uses standard 100 Base-T Ethernet wiring
to provide very fast access to controllers and their data points. The Watlow EtherCAT® Adapter conforms to
the EtherCAT® Temperature Controller Specific Device Profile ETG 5003-2060. It has been conformance tested
by an ETG test facility.
EtherCAT® provides access to system parameters using a CAN open interface scheme. The ETG 5003-2060
specification describes the data point organization. The data is accessed via SDO (Service Data Objects) during
startup and configuration and via PDO (Process Data Objects) exchange during operation. SDO access is
transactional in nature, the master asking for or setting a value in the slave device. The device supports
reading and writing an entire index in one transaction. The feature is called SDO complete. PDO data is a
continuous stream of data from the master and back from the devices at high speed.
USB and Bluetooth® interfaces are provided for configuration and system monitoring from a PC or tablet
devices. Bluetooth® is an option so it can be excluded for production equipment where wireless security is
important.
The Watlow EtherCAT® Adapter can also host a legacy communications adder card. This card provides
additional connection points for Modbus®, DeviceNet™and Watlow Standard Bus. These cards are intended
to extend the network beyond RM modules to include displays like Watlow Silver Series and EZ-ZONE EZK and
legacy controllers such as the EHG® SL-10. The Watlow EZ-ZONE ST and EZ-ZONE PM may be integrated from
the “C” connector without requiring a Legacy Communications card.
The Watlow RMZ4 EtherCAT® Adapter operates within a larger RM system. The RMZ4 part number defines the
number of loops supported. The largest system supported is 48 loops. The RMZ4 module does not support ad-
hoc RM modules and function block programming. Function blocks in the RMS and RME I/O modules may be
programmed using EZ-ZONE Configurator software via the USB port.
The RMZ4 supports 4 optical temperature sensors for high RF or voltage environments like plasma, power
distribution transformers, or medical imaging.

FIGURE 3 –CONNECTIONS POINTS FOR RMZ4-XX04-AAAA WITH OPTICAL TEMPERATURE SENSING
The RMZ has an option for using fluorescent decay via fiber optic cable for sensing temperature in high RF
environments. The number of channels of optical sensing is defined in the model number xxxx-xx04-xxxx.
The fluorescent probes are available from Watlow. The range is generally -100 to +200C without special probe
construction. Each probe is connected via a bayonet style ST connectors. To use this input in a control loop
define the bus as Optical (option 4) and select instance 1, 2, 3, or 4.
