Parameters on the Recipe screen include:
Recipe Name
Type the name of the new recipe being created.
Seg#
Ramp Time
Recipe segments 1 through 8 may be programmed, each with its own set of events, ramp and soak times, and soak temperature.
The time required to ramp setpoint up to temperature may be programmed here. Values between 0 and 99:59 are allowable. As in the Protocol Plus controller, profile ramp and soak times are stored without units. Units are independently set locally, in the actual controller, as either hours and minutes (HH:MM) or minutes and seconds (MM:SS).
EV1 through 4 From 1 to 4 events may be programmed into the ramp time portion of each segment here. These typically involve actuating/disabling relays to close/open valves or perform other relay-controlled functions. NOTE: These will only actuate when the controller has the relay cards installed and programmed for an event. Recipes may contain four Ramp and four Soak event choices, although only those relays actually supplied in a Protocol Plus controller and configured for events will be affected by recipe settings, when used to run a profile.
Soak Temp.
Soak Time
The temperature of a particular segment is entered here; it can range from -18 to 540 degrees C (0 to 1000 degrees F). See Notes on Soak Temp and Hi Limit SP, below.
The duration of soak is entered here; the value can range from 0 to
99:59.

If the process temperature deviates from the setpoint by more than this value, the timer is placed in a hold condition. The timer continues when the process temperature falls within range.
The high limit setpoint may be entered here; if the temperature exceeds this value, the hi-limit will alarm and shut off the heater. See
Notes on Soak Temp and Hi Limit SP, below.
These values enable the profile or controller to jump from a certain step to another step of the recipe a preset number of times.
Link to Profile
Values for the end of profile option are:
STOP Stop oven operation

– 8 Jump to selected profile number
STBY Enter standby mode. See note on Standby Mode below.
Temp. Units
Selects degrees Fahrenheit or Centigrade, for the recipe display only. Recipes stored on the host PC, like profiles in the Protocol
Plus, are always stored with temperatures in degrees Fahrenheit, regardless of the selected viewing units. Note that changing the display units converts displayed recipe temperatures accordingly.
OPEN/SAVE
(to Folder)
These buttons enable the operator to open a new recipe, or save the current one to a predetermined folder.
READ/WRITE
(to Controller)
These buttons enable the operator to upload a recipe from one of the Protocol Plus controllers in the system, or to write the current recipe to one of the controllers.
Profile
Number
Selects which of the Controller's eight profiles is used when reading or writing recipes.
Notes on Soak Temp. and Hi Limit SP Values
In the recipe editor screen, Soak Temp and Hi Limit SP values can be adjusted in the range of -18 to 538 C (0 - 1000 F). Errors may occur attempting to download a recipe to a Controller's profile if one of the recipe's ramp times, soak temperatures, or the high limit setpoint value is incompatible with the range set internally for the target controller.
In this case, an error message similar to Figure 23 will be displayed, and no changes
will be made to the Controller's profile.

Profiles can be started remotely by profile number only if the "Start Profile by Number" option is chosen as shown above. If the "Start Profile by Recipe Name" option is chosen in this window, starting a profile will require selection of a recipe, by name, from
28
Protocol Manager Software E-100 the "Selectable Recipe Files" list that will be displayed in the controller start window
(see "Starting the Controller").
29
Protocol Manager Software E-100
Datalog Functions
Datalog files are maintained to periodically record controller data to a disk file for future analysis. Protocol Manager can maintain two different types of datalog files from networked controllers.
Profile Datalogs
– are initiated automatically when a controller is remotely started running, and are closed automatically when the controller stops running. Profile datalogs are useful for jobs that are based on a specific process run.
Log Datalogs
– are initiated, and subsequently closed, manually, using the Controller
Run Time Window, regardless of the controller's running status. Log Datalogs are useful for jobs that are not related strictly to an entire, single process run.
Both types of datalog files will contain header information, followed by periodic data records. Header information and record data are set for both types of datalogs in the
Profile Datalog Window. Both types of files will be stored in the Log File Folder path indicated in the Profile Datalog window.
The Profile Datalog window also allows setting file naming options and log entry interval options for Profile Datalogs.
The Lot Datalog window is used to enable Lot Datalogs, and set the Log Entry interval specifically for Lot Datalogs.
30
Protocol Manager Software E-100
The Profile Datalog and Lot Datalog screens are accessed from the tabs at the right
side of the initial Recipe Editor screen, off the Recipe/Datalog Window. See Figure
Figure 27: Profile Datalog Window
Select the parameters to be written to the datalog by checking the boxes on the Profile
Datalog Window screen.
Log File Header Information
Check the following boxes to select the types of data to be written into the log file header:
Controller Name
Start Date and Time
Operator ID
Lot Information
31
Protocol Manager Software E-100
Log File Record Data
Check the following boxes to select the types of data to be written into the log file itself:
Elapsed Time
Entry Date and Time
Temperature Setpoint
Temperature Value
Alarms and Events Status
Recipe Name
Log File Folder
This field displays the folder used to store datalog files.
Log At Intervals/Log at Profile Change
These buttons determine whether data will be logged at a certain time interval (see Log
Entry Interval, below), or if data will be logged at every change point programmed into the recipe (start point, beginning of ramp, beginning of soak, etc.). Select one of these logging options depending on the detail level required, and the amount of disk space available for log records. Typically, a short run with few steps might use the time interval option, and a long run with many steps might use the profile change option.
Log Entry Interval: This value controls how often data is logged into a local disk file when selected for a running controller. For example, if two minutes is selected, data will be logged from each running controller approximately every two minutes; it does not mean that all controllers will be polled for data within a two minute period.
The minimum usable interval depends on the number of controllers in the network.
Typically, the minimum interval, in seconds, can be approximated by Tmin = 4 + N, where N = number of Controllers on the network.
Datalog files take up storage space. Typically, a log file's header contains from 10 to up to about 250 bytes, plus Lot Information (Lot Information contains from 0 to 576 bytes), depending on which header information is selected. Each logged data entry contains up to 50 bytes, depending on which data is selected. One running controller, logging data every 15 seconds, would produce a datalog growing at a rate of about 11
Kbytes per hour. 11 Controllers running at this rate would consume about 1 Mbyte of storage every 8 hours.
The datalog is enabled by the Enable Datalog checkbox in the Run Time Window
(described later in this manual).
32
Protocol Manager Software E-100
Log File Naming Options
Log file names consist of a Controller ID and Time Stamp, created when a data log is started.
Controller ID
Controller ID identifies the controller by address (three digits with leading zeroes) or name. If name is selected, blank spaces and characters not legal for use in a Windows file name are converted to underscore characters.
Time Stamp
Select the time format used for the log entries.
Notes on Log File Naming Options
The Controller ID and Time Stamp are combined, but separated by an underscore character, to create a datalog file name prefix. The file name is automatically appended with a ".log" extension.
For a controller named "East Fab #1" with an address of 2, a datalog file name would either begin with "002" (if Address selected) or "East_Fab_#1" (if Name selected).
For a run started on February 4th, 2000, at 2:13:45 pm, the Time Stamp would be either "000204" (if YYMMDD selected), "00020414" (if YYMMDDhh selected),
"0002041413" (if YYMMDDhhmm selected), or "000204141345" (if YYMMDDhhmmss selected).
If "Name" and "YYMMDDhh" were selected, the complete file name prefix would be
"East_Fab_#1_00020414", and the new datalog filename would be
"East_Fab_#1_00020414.log". If a file with that name already existed, however, the new file would be renamed "East_Fab_#1_00020414_1.log".
When a datalog is started, and a filename is created, duplicate filenames are checked for; if a file with the created name already exists, the new filename's prefix has an underscore and a numerical value appended to it to create a unique filename.
33

WARNING
Electronic components are extremely sensitive to static electricity. Before opening the controller case, read and follow the precautions below to prevent damage from static electricity.
1. Turn off power to the controller.
2. Touch a bare metal surface on the exterior of the controller.
3. Disconnect the power connection from the controller or unplug from the power source.
Also follow these static electricity precautions:
Avoid static-causing surfaces while working with electronic components.
Remove parts from their anti-static bags only when ready for use. Do not lay parts on the outside of the anti-static bag because only the inside provides protection.
Hold circuit boards by their edges or any metal mounting hardware. Avoid touching components or connectors on the circuit boards.
Communication Card Installation
1. Turn off power to the controller.
2. Remove the back cover of the controller by removing the two screws at the top of the unit.
3. Looking into the back of the controller with the connector terminal strips at the bottom, install the communication card onto the two 5 pin headers on the rear circuit board. Be sure the jumper blocks on the communication card are
the headers.
4. Set the jumpers on the communication card for the desired serial
communication interface based on Figure 38: Communication Card Jumper

Connecting Protocol Plus Controller(s) to a Communications Host PC
Single Oven
If the oven purchased was not supplied with communication option, order Despatch RS-
232 communication kit P/N 161968. This kit contains all the parts required for one oven to host PC via RS-232 including: Protocol Plus add-on communications board, oven internal cabling, 25 foot null modem cable and Modbus protocol instruction manual.
For single oven communication, the Protocol Plus controller should be configured for
RS-
232 connection. Connect the host PC’s RS-232 COM port to the oven’s communication port using a null-modem cable. Despatch P/N 161971 provides a 25 foot null-modem cable. Refer to Protocol Plus Manual for communication card jumper and controller configuration settings.
Multiple Ovens
If the ovens purchased were not supplied with communication option, order Despatch
P/Ns 141820, add on Protocol Plus communication board, and 161950 (the internal cabling) to make the ovens communication-ready including DB9 external cable connections. Order Despatch P/N 161955 for the components required to network two ovens to a host PC. This kit includes RS-232 to RS-422/RS-485 bi-directional adapter, cabling, and Protocol-specific termination plugs.
Generically speaking, the following description details the steps necessary to network multiple Protocol Plus controllers:
The host PC must have its assigned RS-232 COM port connected to a RS-422/RS-485 bidirectional adapter, for example a “B&B Electronics” adapter Despatch P/N 161938-
40. These P/Ns provide the adapter, power supply and PC-to-adapter serial cable.
The following wiring description refers specifically to the B&B device, but may be applied to acceptable substitute devices.
The Protocol Plus controller’s optional communication card should be configured for
RS-422A 4-wire connection. Set the dipswitches and jumpers on the adapter to match the communication from the host PC RS-232 COM port to the adapter. Wiring from the
B&B adapter’s RS-422A RS-485 terminals is daisy-chained to each of the Protocol Plus controllers. Connect the power supply pigtail leads from the adapter wall mount transformer into the +12V and GND on the adapter. Plug the transformer into a standard 120V / 60 Hz supply outlet.
It is important to note that the communication ready ovens are supplied with two DB9
44
Protocol Manager Software E-100 network ports; “Communication In” and “Communication Out”. For shorter networking runs, standard serial communication rated cables are available in a variety of lengths.
For example; Despatch P/N 161970 is a 25 foot serial cable. DB9 termination plugs are also available from Despatch including P/N 161969; the required termination for a RS-
422 4-wire network. See remaining information if longer network cable lengths are required.
Typically, RS-422A/RS-485A cables consist of three individually shielded twisted pairs; one pair transmits data from the Host PC to the ovens, one pair transmits data from the ovens to the host PC, and one conductor from the third pair is the signal common. The remaining conductor of the third pair is unused. Cable such as Belden type 9843 should be used.
The network requires a cable breakout junction box near each oven. 120 ohm terminating resistors must be installed at each end of the RS-422/RS-485 network.
Refer to the following page for a simplified network wiring diagram. In this case, "To
Host PC" actually indicates a cable connection to the B&B adapter. The "PC Rcv" and
"PC Xmit" terminals refer to the B&B adapter's RD and TD terminals respectively.
Install the 120 ohm resistor between the RD+ and RD- terminals. Connect the GND wire to the 422/485 GND terminal. The remaining termination resistor is applied at the
RD+ and RD- terminals of the “last in line” networked oven.
RS-422/RS-485 allows communication over wires up to 1000 meters in length. It is important to note that the associated runs from the oven’s Protocol Plus controller to the breakout junction box be limited to 5 meters maximum. The junction boxes provide a drop from the network cable to each oven. The cables marked “to Oven Controller” are terminated with 9pin male subminiature “D” plug for mating with the oven controller’s Communication In” serial data receptacle.
Wire drop the cable according to the following table:

Rcv+
Junction box terminal 9-pin plug pin number
5 2
Rcv-
4 7
Xmit+

The daisy chain drop cables may use shielded pairs. Cable shields should be connected as follows:
At each junction box - to the box interior chassis.
At each drop cable 9-in plug-to the lug shell if conductive.
If a non-conductive shell is used, no connection is required.

Controller Hardware and Cabling
Check the communications card
The card needs to be installed correctly (jumpers are on the bottom of the card and should be facing the green terminals)
The jumpers need to be setup for RS232 or RS422, depending on the interface being used. See Modbus User’s Programming manual (E102) for proper settings.
Check cabling between the controller and outside of oven
The R+ should be connected to terminal #1 on the back of the controller. Check with an ohm meter that pin #2 on the 9 pin connector on the outside of the oven is connected to this terminal.
The R- should be connected to terminal #2 on the back of the controller. Check with an ohm meter that pin #7 on the 9 pin connector connected to this terminal.
The T+ should be connected to terminal #3 on the back of the controller. Check with an ohm meter that pin #3 on the 9 pin connector connected to this terminal.
The T- should be connected to terminal #4 on the back of the controller. Check with an ohm meter that pin #4 on the 9 pin connector connected to this terminal.
The SG should be connected to terminal #5 on the back of the controller. Check with an ohm meter that pin #5 on the 9 pin connector connected to this terminal.
Check cabling between the computer and outside of oven
RS232 INTERFACE
The cable running from the Oven’s 9 Pin connector and the computer should be a null modem cable (for a PC with a 9 pin connector, pin 2 at each end connects to pin 3 at the other end, and the cable requires a female 9 pin plug at the PC end and a male 9 pin plug at the Oven end).
