eESPA parameters 281

If the value *CALC is specified, some alarms receive a reset, and other

alarms not. Therefore the eKERNEL application checks to determine if the

alarm description with remove after *SENT exists. If so, this alarm type is

processed, otherwise the alarm is processed as if remove after *RESET

is specified.

If the alarm description is not configured in the eKERNEL_ALARM table,

the alarm is not processed.

An authorized of an entry typically found in this field is as follows: *SENT

eESPA_NAK_retry_cnt_n

This field specifies the number of retries to re-transmit a message after

receiving a NAK.

A device that has control of the communication line can transfer

data to the other devices. When unable to accept the message, the

receiving device sends a negative acknowledge with a (1 or 2 or 3) NAK

sequence, and the sending device can then retransmit the block. If, after

eESPA_NAK_retry_cnt_n attempts, the transmission still fails, and the

sending device terminates transmission with the EOT character.

An authorized of an entry typically found in this field is as follows: 2

eESPA_Timeout_n

This values specifies in seconds how long the station waits, if no valid

transactions are detect on the communication line, before sending a EOT

and terminate the communication and regain control.
