Communication setup with PH201G (style B) distributor (service code 60)
This communication is a one-way to PH201G (Style B) distributor, a power supplier for the EXA 202
transmitters. The PH201G (Style B) receives a current signal (4-20 mA DC) and a digital signal superim-
posed on the DC signal. In other words, the PH201G (Style B) provides a measurement signal, a hold-
contact signal and a fail-contact signal. The communication with PH201G (Style B) is set in Service code
60.
Code 60 *COM The settings should be adjusted to suit the communicating device connected to the out-
put. The communication can be set to HART® or to PH201G (Style B) distributor.
When used with our PH201G (Style B) you can enable or disable contact outputs,
namely, Fail contact and Hold contact. The PH201G (Style B) can output Hold contact
and Fail contact signals. You can set Service Code 53 to “0” for “soft fail” to disable
Fail contact output. When you set Service Code 53 to “1” for “hard fail”, set Service
Code 60 to “2.0” to enable Fail contact output of PH201G (Style B), or set Service
Code 60 to “0.1” to disable Fail contact output of PH201G (Style B).
*ADDR Select address 00 for point communication with 4-20 mA transmission. Addresses 01 to
15 are used in multi-drop configuration (fixed 4 mA output).
