Using The Output Holder With MOD 30ML

MOD 30ML Application

menu will appear with the tag name you gave the output holder compound. Select

that tag and hit “OK”. A new menu will appear with the attribute “RUNINIT” in it.

Select “RUNINIT”. The connection is now complete. Release the connection tool by

clicking the right mouse key.

12. Double click on the oval loop block to return to the compound block. Enter all of the

necessary engineering values in the Input Conditioning and PID blocks.

NOTE: Caution must be exercised if reassigning I/O in the output holder strategy. The

execution order for the blocks of this strategy are specific for the configuration to

work properly. Table 2 shows an example of block execution order.

Table 2. Block Execution Order

Tag Name Type Exec Occur

PV AIN 0 1

pv_i VCI 1 1

RETURN AIN 2 2

SENSE DIM 3 1

RETURNF1 VCI 4 2

SENSF DI 5 1

#001 CIB 6 0

OP_T_LGC EX 7 1

pid PID 8 1

op_ao AOUT 9 1

disp DISP 10 1

TL_ctrl LT 11 1

Notes DESC 12 0

Note that the process variable input, Return input, Sense input, and OP_T_LGC

expression block must run prior to the PID block. The Return and Sense inputs must run

prior to the OP_T_LGC expression block. The PID block must run prior to the analog

output. If using the PID and Output Holder compound and making new I/O assignments,

be sure the block execution order is as shown in Table 2.

Block execution order can be altered using the Execution/Occurrence tool

located on

the top menu, left side.

1. Click once on the

tool and select “manual”. A table will appear that shows the

execution order and occurrence numbers.

2. Change the block execution order by selecting the execution order field next to the

block you wish to change and entering the appropriate execution values. Remember

that no two blocks can have the same execution order number. If you change one

block to read an execution order number that is currently assigned to that of another

block you must also change the original block with that number.
