ONBOARD HART PORT The on-board HART port is functional on the EQP OPECL, however, it should not be used for device configuration purposes.
  • Page 45 SETTING NETWORK ADDRESSES Overview of Network Addresses Each OPECL receiver on the EQP LON must be assigned a unique address. (Since transmitters do not reside on the LON, no network address switch setting is needed.) Addresses 1 to 4 are reserved for the EQP controller. Valid addresses for field devices including OPECL gas detectors are from 5 to 250.
  • Page 46 Do not assign duplicated addresses. Duplicated addresses are not automatically detected. Modules given the same address will use the number given and report to the controller using that address. The status word will show the latest update, which could be from any of the reporting modules using that address. After setting address switches, record the address number and device type on the “Address Identification Chart”...
