Reference Manual Section 2: Installation 00809-0100-4697, Rev GA November 2014 2.3 Wiring If the sensor is installed in a high-voltage environment and a fault condition or installation error occurs, the sensor leads and transmitter terminals could carry lethal voltages. Use extreme caution when making contact with the leads and terminals. Note Do not apply high voltage (e.g. AC line voltage) to the transmitter terminals. Abnormally high voltage can damage the unit (bus terminals are rated to 42.4 VDC).

Reference Manual Section 2: Installation 00809-0100-4697, Rev GA 2.3.2 November 2014 Power supply Connections The transmitter requires between 9 and 32 VDC to operate and provide complete functionality. The DC power supply should provide power with less than 2% ripple. A fieldbus segment requires a power conditioner to isolate the power supply filter and decouple the segment from other segments attached to the same power supply. All power to the transmitter is supplied over the signal wiring.

Reference Manual Section 4: Operation and Maintenance 00809-0100-4697, Rev GA 4.3.3 November 2014 Resetting the configuration (RESTART) There are two types of restarts available in the Resource Block. The following section outlines the usage for each of these. For further information, see RESTART in Table 3-2 on page 3-25. Restart processor (cycling) Performing a Restart Processor has the same effect as removing power from the device and reapplying power.

Reference Manual Appendix C: FOUNDATION Fieldbus Technology 00809-0100-4697, Rev GA November 2014 The Fieldbus Foundation specifications and definitions allow vendors to add their own parameters by importing and subclassing specified classes. This approach permits extending function block definitions as new requirements are discovered and as technology advances. Figure C-1 illustrates the internal structure of a function block.

Additionally, human interface devices, such as operator consoles and computers, do not have to be programmed specifically for each type of device on the bus. Instead their displays and interactions with devices are driven from the device descriptions. Device descriptions may also include a set of processing routines called methods.

Appendix C: FOUNDATION Fieldbus Technology Reference Manual November 2014 00809-0100-4697, Rev GA LAS parameters There are many bus communication parameters but only a few are used. For standard RS-232 communications, the configuration parameters are baud rate, start / stop bits, and parity. The key parameters for H1 FOUNDATION fieldbus are as follows.  Slot Time (ST) – Used during the bus master election process. It is the maximum amount of time permitted for device A to send a message to device B.

Appendix C: FOUNDATION Fieldbus Technology Reference Manual 00809-0100-4697, Rev GA November 2014 FOUNDATION fieldbus uses addresses between 0 and 255. Addresses 0 through 15 are reserved for group addressing and for use by the data link layer. If there are two or more devices on a segment with the same address, the first device to start up will use the assigned address. Each of the other devices will be given one of the four temporary addresses.

A single iteration of the link-wide schedule is called the macrocycle. When the system is configured and the function blocks are linked, a master link-wide schedule is created for the LAS.

In Auto mode, OUT reflects the value and status quality of the PV. In Man mode, the OUT status constant limit is set to indicate that the value is a constant and the OUT status is Good.

Reference Manual Appendix D: Function Blocks 00809-0100-4697, Rev GA November 2014 If the OP_SELECT is set to a value between 1 and 8, the selection type logic is overridden and the output value and status is set to the value and status of the input selected by OP_SELECT. SELECTED will have the number of selected input unless the SELECT_TYPE is mid, in which case it will take the average of the two middle values. Then SELECTED will be set to “0” if there is an even number of inputs.
