FC 56 - Executive Block (NAMM01)

Executive block function codes define several variables that affect module operation. Function code 56 pertains only to the NAMM01 Analog Master Module. Function code 56 resides in fixed block 75 and produces no usable outputs.

 

NAMM02 modules use function code 71, not function code 56.

Explanation

 

NAMM01 Analog Master Modules have up to 72 high level analog inputs. They have eight inputs on board with the capacity to handle 64 others through analog slave modules. Exception reporting times are specified for each group of eight inputs

 

 

Specifications

 

S1 - CNFLOK

(Configuration lock) Specification S1 is the configuration

lock. A one locks the configuration. The default value of block

address zero provides unlocked configuration. Once locked, a

configuration cannot be unlocked. To change a locked configuration,

the module must be initialized and reconfigured.

 

S2 - ALRMDB

(Alarm deadband) Specification S2 defines the alarm deadband

in percent of span for all high and low alarm reports in

the specified module. Alarm deadbands prevent excessive

alarm reports when values hover around the alarm limit.

 

S3 - S36

(Minimum and maximum exception reporting times for

blocks one through 72)

 

MIN - Minimum Exception Report Time

Minimum exception report time defines the minimum interval

between updates of information sent on the communication

highway. Exception reports are not sent on the loop at each

minimum exception report interval unless the value has

changed a significant amount since the last exception report.

Exception report time is selected in 250 millisecond increments

with the default value set to one report per second.

 

MAX - Maximum Exception Report Time

Maximum exception report time defines the maximum interval

between updates of information sent on the communication

highway. If a value of a point has not changed by a

significant amount over this time period, a report of its current

value is automatically sent on the loop. Select exception

report time in 250 millisecond increments. The default value

is one report per minute.
