2 Resource Block
A Resource Block contains all the data that uniquely identifies and characterizes 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 most important functions and parameters of the Resource Block are listed below; you will find
an overview of all the available parameters starting on page 108.
2.1 Selecting the operating mode
The operating mode is configured via the MODE_BLK parameter group. The Resource Block
supports the following operating modes:
!
Note!
The block status OOS is also shown via the parameter BLOCK_ERR.In operating mode OOS, if write
protection is not enabled, you can access all the write parameters without restriction.
2.2 Block status
The current operating status of the Resource Block is shown in the parameter RS_STATE.
The Resource Block can take on the following states:
2.3 Write protection and simulation
Write protection of the device parameters and simulation in the Analog Input and Discrete Output
Function Block can be locked or unlocked via a jumper setting on the FOUNDATION Fieldbus
I/O board (→ Operating Instructions, Proline Promass 83 FOUNDATION Fieldbus, BA065D).
• AUTO (automatic mode)
• OOS (out of service)
• STANDBY The Resource Block is in the OOS mode.
It is not possible to execute the remaining blocks.
• ONLINE LINKING The connections configured between the function blocks have not
yet been linked.
• ONLINE Normal operating status, the Resource Block is in the AUTO
operating mode. The configured connections between the function
blocks have been established.
