6.2.2 How to Implement and Test Any ASP ProtoCessor
• The OEM provides the Modbus register list for the product that the ASP-485 will be designed into.
• MSA Safety programs, configures and tests the gateway with the Modbus register list that was provided to support
BACnet MS/TP. The ASP is not field programmable so the OEM must do the testing for configuration on the
ProtoCessor FPC-ED2. Most customers will want a proof concept before designing the ProtoCessor socket onto their
hardware. The ProtoCessor allows OEMs to quickly create a proof of concept to provide their management team.
• MSA Safety ships a pre-programmed sample of a ProtoCessor FPC-ED2 with all the configurations for the OEM’s
product lines.
• MSA Safety schedules a 60-minute walkthrough for setup and validation.
• The OEM connects their device to the ProtoCessor via RS-232 or RS-485. The OEM can also wire TTL signals that
come off their micro controller and connect them to the ProtoCessor TTL socket. All of this can be done without
designing a ProtoCessor socket.
• MSA Safety provides a BACnet Explorer that allows the OEM to fully test their product on BACnet MS/TP from their
office.
• Once the proof of concept is completed, the customer sends MSA Safety the csv file from the ProtoCessor:
◦ No more changes to the config
◦ Customer starts ProtoCessor socket board spin
◦ Customer needs to purchase the PIC development tools
◦ MSA Safety sends the customer the preprogrammed ASP
• MSA Safety creates an ASP part number in Quick Base.
• MSA Safety gets a blanket order.
• The OEM’s board comes back with the ProtoCessor socket on it.
• To validate the new hardware, the OEM can take the FPC-ED2 module off the ProtoCessor and put it on their new
hardware to validate that the hardware is complete/functioning.
• The OEM then puts the ASP-485 on the hardware and validates it with the BACnet Explorer to test that everything is
working.
• The ASP-485 programming may need some scaling correction. When changes are needed:
◦ The OEM must inform MSA Safety what alterations are required for each point
◦ MSA Safety’s engineers will reprogram the ASP with the changes requested
◦ MSA Safety sends the OEM a binary image to reprogram the ASP using the PIC tools
◦ This process continues until no more changes are needed
• MSA Safety freezes the code.
• MSA Safety ships the first production order.
• MSA Safety provides an installation manual, showing how to install the product on BACnet.
• MSA Safety provides customized webinar training for the OEM’s support team such as how to install and diagnose
problems in the field.
