APPENDIX 1. LIST OF PARAMETERS FOR EACH BLOCK OF THE EJA
20 1020 Scheduled CYCLE_SEL Used to select the block execution method for this resource. AUTO
21 1021 3200 (100ms) MIN_CYCLE_T Time duration of the shortest cycle interval of which the
resource is capable. –
22 1022 0 MEMORY_SIZE Available configuration memory in the empty resource. To
be checked before attempting a download. –
23 1023 0 NV_CYCLE_T Interval between writing copies of NV parameters to non-
volatile memory. Zero means never. –
24 1024 0 FREE_SPACE Percent of memory available for further configuration. EJA
has zero which means a preconfigured resource. –
25 1025 0 FREE_TIME Percent of the block processing time that is free to process
additional blocks. EJA does not support this. –
26 1026 640000 (20S) SHED_RCAS Time duration at which to give up on computer writes to
function block RCas locations. Supported only with PID
function. AUTO
27 1027 640000 (20S) SHED_ROUT Time duration at which to give up on computer writes to
function block ROut locations. Supported only with PID
function. AUTO
28 1028 1 FAULT_STATE Condition set by loss of communication to an output block,
failure promoted to an output block or a physical contact.
When fail-safe condition is set, Then output function blocks
will perform their FSAFE actions. –
29 1029 1 SET_FSTATE Allows the fail-safe condition to be manually initiated by
selecting Set. AUTO
30 1030 1 CLR_FSTATE Writing a Clear to this parameter will clear the device fail-
safe state if the field condition, if any, has cleared. AUTO
31 1031 3 MAX_NOTIFY Maximum number of unconfirmed notify messages possible. –
32 1032 3 LIM_NOTIFY Maximum number of unconfirmed alert notify messages
allowed. AUTO
33 1033 640000 (20s) CONFIRM_TIM The minimum time between retries of alert reports. AUTO
34 1034 Not locked WRITE_LOCK If set, no writes from anywhere are allowed, except to clear
WRITE_LOCK. Block inputs will continue to be updated AUTO
35 1035 – UPDATE_EVT This alert is generated by any change to the static data. –
36 1036 – BLOCK_ALM The block alarm is used for all configuration, hardware,
connection failure or system problems in the block. The
cause of the alert is entered in the subcode field. The first
alert to become active will set the Active status in the Status
attribute. As soon as the Unreported status is cleared by the
alert reporting task, another block alert may be reported
without clearing the Active status, if the subcode has
changed. –
37 1037 Enable ALARM_SUM The current alert status, unacknowledged states, unreported
states, and disabled states of the alarms associated with the
function block.
Version number of interoperability test by Fieldbus
Foundation applied to EJA.
