11.2 Resource Block

A Resource Block contains all the data that uniquely identifies and characterises the
field device. It is an electronic version of a nameplate on the field device. Parameters of
the Resource Block include device type, device name, manufacturer ID, serial number,
etc.
A further task of the Resource Blocks is the management of overall parameters and
functions that have an influence on the execution of the remaining blocks in the field
device. The Resource Block is thus the central unit that also checks the device status
and thereby influences or controls the operability of the other blocks and thus also of
the device. Since the Resource Block has no block input and block output data, it
cannot be linked with other blocks.
The major functions and parameters of the Resource Block are listed below; you will find
an overview of all the available parameters starting on page 113.

11.2.1 Selecting the operating mode

The operating mode is set via the parameter group MODE_BLK (see page 116). The
Resource Block supports the following operating modes:
– AUTO
– OOS
Note:
The block status OOS is also shown via the parameter BLOCK_ERR (see page 114). In
operating mode OOS, if write protection is not enabled, you can access all the write
parameters without restriction.

11.2.2 Block status

The current operating status of the Resource Block is shown in the parameter RS_STATE
(see page 116).
The Resource Block can take on the following states:
– STANDBY
– ONLINE LINKING
– ONLINE
FOUNDATION Fieldbus temperature transmitter
The Resource Block is in operating mode OOS. The
remaining blocks cannot be executed.
The connections configured between the function blocks
have not yet been linked.
Normal operating status; the Resource Block is in operating
mode AUTO. The connections configured between the
function blocks have been linked.
