1. Scope
This purpose of this document is to provide an introduction to the MicroVisionEX
Controller and its Modbus TCP/IP capabilities. The intent is to provide a Modbus
developer with the information needed to interface the controller with a typical
Supervisory Control and Data Acquisition (SCADA) system.
2. Introduction
MicroVisionEX is a microprocessor based cooling tower controller designed to
monitor and control water quality parameters within the circulated tower water.
MicroVisionEX determines the TDS present in the tower water via a measurement of
water conductivity.
Some MicroVisionEX models can also measure and control the tower water pH and
Oxidation-Reduction Potential (ORP).
Additionally, all MicroVisionEX models come equipped with hardware based Timers
which activate AC relays. These Timers are typically used to dose chemicals into the
tower water and are highly configurable.
Depending on the model, MicroVisionEX is configurable using one or more of the
methods listed below:
Using buttons present on the MicroVisionEX front panel
By importing a configuration file via the MicroVisionEX Universal Serial Bus
(USB) interface
Using PULSAlink – A cloud based IoT application with PC and Mobile Apps
designed to provide remote status and control capabilities.
All MicroVisionEX models equipped with an Ethernet interface can connect to a
SCADA system via the Modbus TCP Compunction protocol. MicroVisionEX supports
simultaneous connections to both a Modbus master and the PULSAlink IoT cloud
application. MicroVisionEX serves as a Modbus slave / client and can provide a
Modbus master / server with the controller’s current configuration settings and its
operational status parameters.
The following sections within this document provide a Modbus developer with the
MicroVisionEX memory map and other relevant interface information.

3. Connections and Installation
Modbus Interface Type: Slave / Server
Modbus Protocol Type: Modbus TCP
Modbus Address: 99
Connection Port: 502
Data Encryption: none
Endianness: big-endian
Number of simultaneous connections: 1
Timeout: 1 Sec.
Function Codes Supported 4 (Read Input Registers)
Notes:
MicroVisionEX supports both Dynamic and Static IP addresses. However, whenever
the Modbus interface is used a static IP address is recommended.
MicroVisionEX employs a secure connection with PULSAlink. When the controller is
configured to use both Modbus and PULSAlink please ensure that your network
supports an internet connection on port 443.
A typical installation is depicted in the figure below.

4. Modbus memory map
The availability and content of the registers listed in the following sections is model
dependent.
The MicroVisionEX Modbus interface is designed to provide a Modbus Master / Client
with controller configuration and status information via Modbus function code 4
(Read Input Registers). The Master / Client is not permitted to modify configuration
parameters within the controller.
