    Once ISOCOMM receives a command from the user, ISOCOMM will transmit the command to the module or PFC section of the iHP. If the user needs data from a module or PFC device, the module or PFC device will transmit data to the ISOCOMM and ISOCOMM will be the one to send data to the user.

  • Page 34: Ihp Digital Communication Identifier

    3.1 iHP Digital Communication Identifier To communicate to the iHP, the user needs to know the iHP address and the specific device inside the iHP system in which the user needs to communicate. ISOCOMM, installed modules and PFC devices function independently inside an iHP system and each device has its own device address as shown in Figure 3-2 and 3-3.

  • Page 35: Ihp Address

    Ethernet Address – depends on the configuration of iHP. IP setting can be Static or DHCP. For Static IP, this will need to be set to an unassigned IP address by the user before integration into a system. For DHCP, the router will assign an open IP address.
