FBM215 P0917TQ Using parameter input module

. If the connection allocation bit 1 (polled) is set (see Step 5 on page 31), refer to Table 3-10 to configure the polled data input format and status byte and Table 3-11 to configure the polled data output format. • You may configure the module to send data to the network in unsigned integer (UINT), or floating point data (REAL) formats, with or without a status byte. • The default configuration sends pressure in floating point data format with one byte of status data.If the connection allocation bit 1 (polled) is set (see Step 5 on page 31), you may configure the module to receive one byte of input data that controls the Micro-Ion Gauge, as listed in Table 3-12.When Bit 0 is set to 1, degas will begin if the ion gauge is ON Enable Filament 1 When Bit 1 is set to 1, filament 1 will turn on if the ion gauge is ON Enable Filament 2 When bit 2 is set to 2, filament 1 will turn on when the gauge is ON. If both bits 1 and 2 are set to 1, both filaments will turn on when the gauge is ON. If both bits 1 and 2 are set to 0, the last programmed value will be used to turn on the filaments. Bits 3 and 4 Reserved - should always be set to 0 Medium Emission 

Pressure Units and Values 

You may use explicit messages to set the pressure unit. You may use explicit messages or input polled I/O to read values that represent measured pressure. You must calculate measured pressure from the values represented by the explicit message or input polled I/O. If you get pressure using input polled I/O or from the assembly object using explicit messaging, values are available with or without warning and alarm status or trip point status. Set or Get Pressure Unit Use the explicit messages listed in Table 3-14 to set or get the unit of pressure.When bit 7 is set to 1, the ion gauge will operate at high emission when the gauge is ON. The state of bit 5 is irrelevant when bit 7 is set to 1. If both bits 5 and 7 are set to 0, the ion gauge will operate at low emission When bit 5 is set to 1, the ion gauge will operate at medium emission when the gauge is ON. Ion Gauge When bit 6 is set to 1, the ion gauge will be ON and allow a reading of pressure. If a fault condition occurs, the state of the ion gauge will be OFF and the fault condition must be cleared before pulling this bit to 0, then 1 again to light the ion gauge.

Get Vacuum Pressure

 You may use explicit messages or input polled I/O to read values that represent measured pressure. You must calculate measured pressure from the values represented by the explicit message or input polled I/O. If you get pressure using input polled I/O or from the assembly object using explicit messaging, values are available with or without warning and alarm status or trip point status. • The explicit messages for each object are listed in Table 3-16. • You must refer to Table 3-15 to convert the BYTE, UINT, INT, or REAL data to meaningful values representing exception status, trip point status, vacuum pressure, or differential pressure.When a master polls the module for measured pressure, the format of the returned pressure value depends on the data type. See Table 3-17. • To configure the data format for input polled I/O, see Step 7 on page 32. • You must refer to Table 3-15 to convert the BYTE, UINT, INT, or REAL data to meaningful values representing exception status, trip point status, vacuum pressure, or differential pressure.
