Remote monitoring and troubleshooting via CHEMCOM® communication program

Program Operation     Remote Screen     Data Log     Bid Spec


The CHEMCOM® software is a proprietary Windows program that offers true duplex operation with identical duplicate screens on both the controller and the computer. This means that every event on the controller or action on the remote computer is immediately reproduced on the other screen. This unique feature is particularly useful for remote monitoring, operator training and troubleshooting, as well as real-time control of all operating functions includes status reports and automatic alerts by email/ or text messages. This also allows real-time supervision by management and remote troubleshooting by any CHEMTROL® Qualified representative/ Dealer.

There are several different ways to connect to the remote controller, each being adapted to specific situations, such as location and availability of communications equipment. It is also possible to interface the controller with a MODBUS protocol directly to a Building Management Systems (BMS).


Most common and recommended for facilities with a local Ethernet computer network. The controller is connected to the network as an additional computer. It can be accessed from any computer on the network that has the CHEMCOM® software program. It can also be accessed from outside the network by connecting to the Internet.


Technical support from CHEMTROL representatives/ or an Authorised Dealer through Internet connection. Possible integration to Building Management Systems (BMS).


Requires a local Ethernet network. Requires Internet connection with static IP address.


The CHEMCOM® remote control program runs under Windows™ operating software from Microsoft. The Main Menu provides the following key functions:

  • SYSTEM SETUP to customize the communications options for the remote computer, such as communication port setting, and alarm limits for each parameter,
  • FACILITIES SETUP to enter the specifics for each remote facility, such as modem and operator phone numbers, model and type of connection,
  • SCANNING SCHEDULE for automatic scanning mode,
  • REMOTE CONTROL to access and operate any of the remote facilities,
  • DATA DISPLAY to show operational data in either graphical ot text format.


The remote computer displays a control screen that is an exact duplicate of the front panel of the controller. It uses the same function keys, menus and sub-menus. This allows easy operation for anyone who is familiar with operation of the controller.

The remote screen gives full access to the controller for monitoring, troubleshooting and operator training.



The operating data stored in the controller can be downloaded directly to the computer and shown either as a scan log, a text file or a graphic display. The data log schedules are selected by the operator. On the scan log shown here, the out-of-range values are highlighted in red. The limits can be reset by the operator at any time before or after data downloading.

The data log text file can be used for operation reports, health department inspections, etc.



GRAPHIC DISPLAY – The operating data from the controller can also be shown in graphic form. The operator can select parameters for display and can zoom in and out for specific dates and times of the day.

Both text and graphic curves can be copied and included in reports or other documents.



1. OPTION ETHCOM: The controller shall include an Ethernet / Internet modem for remote operation by PC-compatible computer using Ethernet / Internet network communication. A Windows-based software program shall be supplied with true duplex operation capability representing the actual controller screen display with automatic downloading and visual graphics representation of test data. Controllers using simulation or virtual representation of the display screen shall not be considered equal.

2. OPTION MODBUS: The controller shall include software-based conversion of sensor signals, setpoint, high & low alarms, cummulative run time and total feed time for ORP, pH, PPM, Temperature, (Conductivity, Pressure influent and effluent, and Flow available with optional sensors) into MODBUS protocol for monitoring on Building Management Systems. The controller shall also allow MODBUS writing for changing control modes and setpoints from Building Management Systems.

3. OPTION 4-20 mA SIGNAL: A five (5)-channel converter board shall be provided to convert the sensor digital signals for ORP, pH, PPM, temperature and conductivity (TDS) into analog 4-20 mA signals for monitoring on Building Management Systems. The board shall be capable of sending a sourcing or sinking type of signal.
