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 major functions and parameters of the Resource Block are listed below; you will find an
overview of all the available parameters starting on Page 73.
2.1
Selecting the operating mode
The operation mode is set by means of 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:
– AUTO (automatic mode)
– OOS (out of service)
– STANDBY
The Resource Block is in operating mode OOS.
The remaining blocks cannot be executed.
– ONLINE LINKING
The connections configured between the function blocks have not
yet been linked.
– ONLINE
Normal operating status; the Resource Block is in operating mode
AUTO. The configured connections between the function blocks
have been established.
