CHAPTER3: THERECIPEEDITORSOFTWARE
TheHornerElectricNetworkInterfaceModule(NIM)servestwopurposesinthePIDnetwork. First,itprovidesan
interface between the PID controllers (PIDs) and the Alspa 8000 PLC. This interface allows the PLC to receive
updates on the current status of control variables and process variables in individual PID controllers. Second, it
storeswithinitsmemoryPIDparameterrecipesandjobs. ThesecanbedownloadedtothePIDsuponcommand
fromthe PLC.
TheNIMoperatesundertwo“modes”ofoperation,ManualandAutomatic. InAutomaticMode,theNIMreceives
itsinstructions fromthe PLC. This isthe normal modeof operation aftera PID network has beeninstalled and is

3.1 What is a “Recipe”?
A recipe is a complete set of PID parameters stored in the NIM which may be downloaded on demand to one or
more PID controller(s). PID parameters stored in the recipe are described in detail in the Horner Electric Stand-
AlonePIDControllersUser’sManual ,andincludethefollowing:
CONTROLLERTYPE CYCLETIMEPIDOUTPUT1 PIDRATE
SETPOINT CYCLETIMEPIDOUTPUT2* LOWERSETPOINTLIMIT
GAINOUTPUT PIDRESETTIME UPPERSETPOINTLIMIT
GAINRATIOOUTPUT RAMP-TO-SETPOINTTARGETTIME
* applies only to PIDs with two outputs.
Upto 41 different recipes can be stored in the NIM. Each recipe must have a unique number, between 0 and 40
inclusive. EachPIDmayuseseveraldifferentrecipes. Also,onerecipemaybesharedbyseveraldifferentPIDs.

To start the software, typePIDNET from the DOS prompt. Figure 3-1 shows the screen layout.
3.5 The Status Bar
The Status Bar is the portion of the screen where the Recipe Editor software displays the current status of the
followingitems:
COM Port. The selected COM port on the computer is displayed, along with its “initialized” (INIT)
or “not initialized” (NOT INIT) status. If the port is not initialized, it is likely that the
port either does not exist or is inoperative. Another port should be selected.
Status. Thisshows the status of the NIM-computer RS-232 connection. The Recipe Editor
software checks periodically to verify the connection. If there is a communications
problem, a “not connected” status will be reported. If the connection is OK, a “con
nected” statuswill be reported.
Mode. While connected, the Recipe Editor software monitors the mode of the NIM, “Auto
matic” or “Manual”. If this mode is changed by the software, the status bar will
indicate the change. If the mode is changed in the PLC configuration while the
software is connected, the status bar will indicate this change as well. If the NIM is
“notconnected”,the software is unable to inquire as to the current NIM mode. In that
case the status bar will always indicate a mode of “manual”.

3.6 AccessingCommandsUsingthePull-DownMenus
The Recipe Editor software utilizes pull-down menus for easy operation. The available menus are accessed by
pressing the<Backspace> key. The<Right>and <Left>arrow keys are used to move the cursor to select the
desired menu. Once the desired menu is highlighted, the<Up> and<Down>arrow keys are used to move the
cursorto thedesired menu item. Pressing<Enter> activates thechosen menuitem command. To exit from the
pull-down menu system without making a selection, press the <Escape> key.
3.6.1 The File Menu
TheFileMenuofferscommandsreleventtostartinganewsession,retrievingandsavinginformationtocomputer
disk, and ending the session. The available commands are as follows:
New. Clears all the recipes and jobs currently resident in the IBM program’s RAM memory. This
commandshouldonlybeusediftheinformationhasbeenpreviouslystoredtodisk,orifitistobe
discarded.
Load. Retrieves recipes and jobs from computer diskette to the IBM program’s RAM memory. This
informationis storedin theprogramPID.DAT. Inorderto savemore thanone setupyou should
copythisfiletoadifferentfilename. Thenwhenyouwishtoretrievethisinformationsimplycopy
your file to PID.DAT. The Recipe Editor software will load this file when the load command is
chosen.
Save. Saves the current recipes and jobs residing in the IBM Program's RAM memory to computer
diskette or the NIM memory. After selecting the Save item, the user is asked whether the
information is to be saved to the NIM or to computer disk. In order to save to the NIM, the
ConnectionStatusmustbe“Connected”.
Quit. This aborts operation of the Recipe Editor software and returns to DOS. This command should
onlybeusediftheinformationresidingintheprogram’sRAMmemoryhasbeenpreviouslystored
to disk, or if it is to be discarded.
3.6.2 The Recipe Menu
TheRecipeMenuallowsnewrecipestobecreated,existingrecipestobeedited,viewed,anddownloadedtothe
appropriatecontroller. Menuitemsinclude thefollowing:
Copy. Thiscommand allows an existing recipe tobe copied into another. This is usefulwhen creating
anewrecipewhich is virtuallyidenticalto another recipe(forinstance, same exceptfordifferent
setpoint). Afterthisitemhasbeenselected,theuserispromptedfortherecipetocopyfrom,and
then the recipe number to copy to.
Edit. This command allows new or existing recipes to be edited. Once this item has been selected,
pop-upwindowsprompttheuserfortherecipe numbertobeedited,andthecontrollerinputand
output types. The cursor is then placed on the recipe parameter list, which the user may
complete. While editing recipe parameters, the <Up> and<Down> arrow keys are used to
navigatethecursortothedifferentparameters. Oncehighlighted,individualparametervaluesare
filled-insimplyby typinginthevaluefollowedbythe<Enter>key. Editingtherecipeiscomplete
whenthe<Escape>keyispressedorwhenthe<Enter> or<Down>arrowkeyispressedwhile
thecursor resideson thefinal parameter,“Upper Setpoint Limit”.

Chapter3:THERECIPEEDITORSOFTWARE Page 5
Download. This command allows a recipe stored in the memory of the NIM to be downloaded to
anindividual PID controller. Notethat the recipemust resideinthe NIMbefore
downloadto a PIDcontroller. Therefore arecipe createdwith theRecipe Editor
software must be saved to the NIM prior to download to a PID controller. SeeSave
undertheFileMenu .
View. The view commandis used to view recipes already created bythe Recipe Editor
software. After selecting this item, a pop-up window will appear indicating the recipe
number displayed. The<Right> and<Left>arror keys are used to increment and
decrement the recipe number as the recipes are perused. Pressing <Escape> exits
recipeviewmode.
3.6.3 The Job Number Menu
TheJob Number Menu allows newjobs to be created, existing jobs to be edited, viewed, and downloaded to the
appropriatecontrollers. Menuitems includethe following:
Copy. This command allows an existing job to be copied into another. This is useful when
creating a new job which is virtually identical to another job. After this item has been
selected, the user is prompted for the job to copy from, and then the job number to
copy to.
Edit. This command allows new or existing jobs to be edited. Once this item has been
selected,pop-up windows prompt the user for the job number to be edited. The cursor
is then placed on the job list, which the user may edit. The job list consists of a list of
PIDs, and the recipes which the PIDs will use for a particular production job. The
PIDs may all run the same recipe, or they may each run different recipes. Setting the
recipe for a particular PID is accomplished in two steps. First, use the <Up> and
<Down> arrow keys to place the blinking cursor on the desired PID number. Then,
use the<Left>and<Right> arrow keys to select the appropriate recipe number for
that PID. When the correct recipe number is displayed for that PID, press <Enter>.
Repeatthe processuntilall the PIDs used for that job are assigned a recipe. Editing
the job is complete when the <Escape> key is pressed.
Download. This command causes a job download to occur from the NIM to the appropriate PIDs.
The NIM will download recipes to PIDs as mapped out by the selected job list. Note
that the jobmust reside in the NIMbefore downloading toPIDs willoccur. Therefore a
job created with the Recipe Editor software must be saved to the NIM prior to down
load to the PIDs. See Save under the File Menu .
View. Theview command is used to view jobsalready created bythe Recipe Editorsoftware.
After selecting this item, a pop-up window will appear indicating the job number
displayed. The<Right> and<Left> arror keys are used to increment and decrement
the job number as the jobs are perused. Pressing<Escape> exits job view mode.
3.6.4 The Change Menu

fortheNIMRS-232connection,andtheStatusoftheconnectionbetweenthepersonalcomputerandtheNIM. The
followingitemsreside on theChangeMenu:

Page 6 Chapter 3: THE RECIPE EDITOR SOFTWARE
Mode. The Mode function allows the user to put the NIM in “Automatic” or “Manual” mode. In
“Manual”mode,theNIMreceivesallcommandsfromtheRecipeEditorsoftwarevia
the RS-232 connection to the personal computer. In “Automatic” mode, the NIM
receives its commands from the PLC CPU outputs. In order to change the mode of
the NIM, the NIM Status must be “Connected”.
Port. The Port function allows the user to select the personal computer COM port used in
the NIM RS-232 connection. Upon selection of this menu item, a pop-up window
appears, prompting the user for the desired port number. Only COM ports 1 thru 4
arelegalvalues. Immediatelyuponreceivingthedesiredportnumber,theRecipe
Editor software attempts to initialize the port. If it is unable to initialize the port, the
port is not valid for that computer and another COM port must be selected.
Status. The Status function when selected attempts to establish a connection between the
computer’s COM port and the NIM module. If it is successful, the Status Bar will
change to indicate the “Connected” status. If it is unsuccessful, the Status Bar will
indicate a “Not Connected” status. A “Connected” status is required before many
functions(such as saving recipes andjobs to the NIM memory) can be performed.
Monitor. This function is used to select color or monochorome mode. If a monochrome
monitor is used, menu use is difficult when the program is setup in color mode.
