Resource Block

A Resource Block contains all the data which uniquely identify and characterise 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 Block 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 parameters available from Page 89 onwards.
2.1

Selecting the operating mode

The operating mode is set by means of the MODE_BLK parameter group,
(see Page 95). The Resource Block supports the following operating modes:
– AUTO (automatic mode)
– OOS (out of service)
Note!
The OOS operating mode is also displayed via the BLOCK_ERR parameter, (see
Page 92). In the OOS operating mode, you can access all the write parameters without
restriction if write protection is not enabled, (see Page 90).
2.2

Block status

The current operating status of the Resource Block is displayed in the RS_STATE
parameter, (see Page 96).
The Resource Block can take on the following states:
– STANDBY
– ONLINE LINKING
– ONLINE
The Resource Block is in the OOS operating mode.
Execution of the remaining blocks is not possible.
The connections configured between the function blocks
have not yet been linked.
Normal operating status, the Resource Block is in the AUTO
(automatic) operating mode.
The configured connections between the function blocks
have been made.
