FC 105 - Executive Block (IMLMM02)

Executive block function codes define a number of variables that affect module operations. Function codes 105 through 108 define various parameters affecting IMLMM02 Logic Master

Module operations. Function code 105 resides in fixed block one of the IMLMM02 module. NLMM01 Logic Master Modules use function code 54, not codes 105 through 108.

105.1   Explanation

 

Function code 105 outputs all IMLMM02 module fixed blocks except those containing segment control information for the resident segment control block (15 through 17), and those containing RAM utilization information (18 and 19).

 

105.1.1  Specifications

 

S1 - BLKADR

Specification S1 is the block address of configure mode lockout flag.

0 = configure mode allowed

1 = configuration locked

 

The default value of S1 is block address zero, which provides unlocked configuration. A logic 1 locks the configuration. Once locked, a configuration cannot be unlocked. To change a locked configuration, the module must be initialized and re-configured.

 

S2 - XRPCNT

Specification S2 is the digital/boolean exception report count. The digital/boolean exception report count defines the number of blocks in the module that have exception reports defined internally. This number of IMLMM02 module outputs can be accessed from the communication highway without defined exception reports (i.e., digital exception report, remote control memory). The internally defined exception report outputs can be accessed from a node in the system (i.e., console, module).

 

S3 - START

Specification S3 is the time delay for local I/O servicing on start-up in seconds. Specification S3 defines the length of time at start-up that I/O values are invalid. It enables the system to start up and begin  generating valid logic information before using I/O for control or other purposes.

 

S4 - MAXBLK

Specification S4 is the maximum configurable block number in the module. The maximum configurable block number is 1,023.  Specification S4 can be used to restrict the configurable block range (i.e., NLMM01 compatibility).

105.1.2   Outputs

 

0

Output block zero equals logic 0.

 

1

Output block one equals logic 1.

 

2

Output block two is reserved.

 

3

Output block three equals -100.0.

 

4

Output block four equals -1.0.

 

5

Output block five equals 0.0.

 

6

Output block six equals 1.0.

 

7

Output block seven equals 100.0.

 

8

Output block eight shows the maximum negative value.

 

9

Output block nine shows the maximum positive value.

 

10

Output block ten shows the start-up complete flag status.

0 = no

1 = yes

 

This output shows that start-up is complete and I/O values are valid. Specification S3 defines start-up time.

 

11

 

Output block 11 is reserved.

12

The output of block 12 shows the percentage of free time left to the module processor.

 

Free time = 100 – total module execution time

 

13

Output 13 is the module revision level. The module revision level is a four digit number identifying the module nomenclature, hardware revision level, and firmware revision level.

 

14

Output 14 is reserved.
