11. Resource Block
11.1 General
The resource block stores device hardware
information related to all function blocks in the same
device, such as the memory size, and controls
the device hardware and internal function blocks.
Regardless of the execution schedule of the
function blocks, the resource block runs at a certain
interval.
11.2 Alarm Processing
The resource block generates a block alarm in the
following cases:
• An error represented by a bit in BLOCK_
ERROR, shown in the table below, has
occurred (identified as a Block alarm).
• A static parameter has been written (identified
as an update event).
• The value of a write-locked parameter has been
modified (identified as Write alarm).

Needs servicing urgently.
15 Out-of-Service The target mode is O/S.
11.3 Device Status
When fault occurs, the corresponding bits in the
parameters DEVICE_STATUS_1 to _3 of the
resource block are set on. Table 11.2 to 11.4 show
the codes and indication corresponding to the
individual bits in DEVICE_STATUS_1 to _3 as well
as the meanings represented.
