Read our Q&A with Advanced Sensor Technologies, Inc. (ASTI) Vice President Thomas Patko about why they chose Maple Systems as part of their HiQDT smart digital sensor solution. The HIQDT smart digital sensors have integral industry standard RS-485 Modbus RTU communications, allowing them to be connected directly with a wide array of devices. ASTI is thus ushering in a new era in industrial field measurement where the brand of data acquisition and control devices are altogether decoupled from the manufacturer of the smart digital sensor, giving true freedom of choice back to the customer.
"I am an Analytical and theoretical electrochemist specializing in design and optimization of analog and smart digital sensors for measurement of pH, ORP, ion selective, conductivity and dissolved oxygen parameters."
"We required a robust HMI & PLC with certifications for use in hazardous locations (if required for a customer installation site) to interface and control the smart digital HiQDT MODBUS RTU sensors for measurement of pH, ORP and dissolved oxygen parameters."
"With this new partnership with Maple Systems, we are expanding the market for smart digital HiQDT Modbus RTU sensors beyond just the OEM and system integrator to also support typical end-user requirements. Now we can provide complete turn-key solutions by mating together the Modbus RTU master device with the smart digital HiQDT Modbus RTU sensor slaves. Typically, key features and functionality requested by end-users were scalable 4-20mA analog outputs, programmable contact relays, and full remote access over ethernet to minimize on-site field visits, as well as email notifications for trigger events. Some OEM and systems integrators also desired a local display as well as Modbus TCP (a.k.a. Modbus over ethernet) instead of the Modbus RTU available directly from the HiQDT smart digital sensors."
"A variety of potential HMI and PLC suppliers were considered. Evaluation was conducted by weighing the available features, prices and certifications for use in hazardous locations. The ability to have more cost competitive versions for non-hazardous locations is a bonus if the software can be binary compatible between the hazardous location version and the safe non-hazardous location version."
"The model HMI5070L was chosen as the HMI for the six (6) channel and three (3) channel touchscreen controller assemblies due to the following key features and functionality:
"The model HMI5043L was chosen as the HMI for the two (2) channel touchscreen controller assemblies due to the following key features and functionality:
"The Maple PLC was chosen as the core PLC module for all of the touchscreen controller configurations (2 channel, 3 channel and 6 channel). The 2 isolated analog outputs and 6 programmable contact relays are employed for all controller configurations.
"ASTI would have been limited to only OEM & system integrator clients. In addition, the ability to construct a robust and complete software solution for use with the HiQDT sensors was crucial for us. Without this, we would not have been able to offer to our prospective OEMs and System Integrators the option to customize the project templates. Now they can easily modify or drop unneeded functionality from projects if they wish."
"For any new product there is the risk of damage to reputation if there are problems with commissioning or ongoing field-use and maintenance issues. We were not familiar with Maple Systems before this project, so we had to assess the risk of starting up business with a new vendor as well, but the choice has paid off."
"Initially we had reservations about our lack of internal resources in terms of HMI & PLC programming. This was solved by a recommendation to a very proficient programmer that was quite familiar with the Maple Systems development tools and hardware. This made it easy for us to implement all the core functionality we needed in the commercialized version of the touchscreen controllers."
"We have received increasing numbers of inquiries from companies that are focused on the Industrial Internet of Things (IIoT) since adding the HiQDT product platform. This includes those that wish to have full remote access capabilities to these measurements for both environmental compliance as well as process control purposes."
"Plans are in place to add conductivity and ion-selective measurement parameters at some point in the future. There is no firm timetable, but we have confirmed that sufficient flash memory is available for all controller configurations to add these additional sensor types."
