ST100 Series Profibus PAFluid Components International LLC 17Using the ST100 PROFIBUS PA Service Transducer BlockIntroduction to the Service blockThe ST100 Service Block provides access to a number of instrument configuration parameters and troubleshooting information. The multi-pointconfiguration mode provides process information from each individual sensor and sensor electronics.Configuration Parameters:FLOW_TYPE: This parameter is a read/write parameter and is used to set and select one of three flow types;velocity flow, or volumetric flow, or mass flow. To set the instrument to velocity flow, a value of4 needs to be entered. To set the instrument to mass flow, a value of 3 needs to be entered. Andto set the instrument to volumetric flow, a value of 0 needs to be entered.TOTALIZER_STATE: This parameter is used to turn the FCI internal TOTALIZER on or off. To turn the TOTALIZER on avalue of 1 needs to be entered. To turn the TOTALIZER off a value of 0 needs to be entered.PLENUM_SIZE_VALUE1: This parameter and the other PLENUM_SIZE_VALUE2 are used to enter plenum sizeinformation when the plenum is a duct. This parameter is used to enter the size of the widthof the duct.PLENUM_SIZE_VALUE2: This parameter is used to enter the size of the height of the duct.WRITE_PROTECT_MODE: This parameter is used to limit or give access to the parameters that can be written from theinstruments other configuration ports. The ST100 has 3 ports that can be used to set it up orconfigure the instrument, a USB port, an Ethernet port and the digital communication protocollike PROFIBUS PA. By loading a value of 1 into this parameter, it inhibits the other ports fromaccessing the setup parameters at the same time that the parameters are being set throughPROFIBUS PA. To release control a value of 0 needs to loaded into this parameter.FACTORY_RESTORE: This parameter is used to restore the current active flow group calibration parameters to thevalues initially set by the factory.Information Parameters:DEVICE_CO: This is a read only parameter that presents the Customer Order number assigned to theinstrument.DEVICE_SERIAL_NUM: This is a read only parameter and it presents the instrument’s serial number.DEVICE_SFTWR_VER: This parameter is a read only parameter and it presents the instruments software version.Troubleshooting Parameters:SENSORS_BANK_1: This parameter allows viewing of the process parameters that the FE (Sensor level) beforeaveraging, allowing technical personnel in the control room the ability to identify thecontribution of each sensor head, and identify the problem sensor.
