2 Known issues
2.1 CAN Bus Off error after turning on a DPC12 (193548)
2.1.1 Description
Othe r d evice s on the bus experience CAN faults which lead s to them declaring a CAN Bus Off error after the DPC12 controlle r is powered on. This causes the devices to stop communicating with the system until their faults are cleared.
The issue may also lead to difficulty using the PLUS+1® Service Tool Recover ECU function as controller is power-cycled during this procedure.
The problem is caused by the power-up behavior of the DPC12 CAN transmitter. When the controlle r is supplied from a current-limite d power supply, the controller can hit this current limit and brown out multiple times during the initial pow er-up. On e ach brow nout an erroneous signal is transmitted on the CAN bus. Multiple b row nouts lead to a high enough error count to trigger the CAN Bus Off error on other connecte d devices.
2.1.2 Solutions
Use a pow er supply with a higher current limit or turn off soft-start behavior.
A hardware solution w ill be implemented in a future DPC12 controller revision.
2.2 J1939 unused references require valid value (369615)
2.2.1 Description
The M anufacturer specific PGNs use d to send the control references and limits to the DDP096 software includ e sig nals for seve ral service s w ithin the same messag e. In the case w here the value for one of the services is not being used (due to the correspond ing source parameter, _SRC, being set to unlimited or PLUS+1®), the DDP096 softw are d oes not accept the correct value for the unuse d signals. To meet the J1939 stand ard the system controlle r should send a "not used/not req uested " value, however upon receiving this value the DDP096 softw are w ill ge nerate an "Invalid d ata in J1939 message" error.
2.2.2 Solutions
Send value of zero instead of the "not used/not requested" value. This should b e zero in the physical units of the message, with the rele vant scaling and offset applied.
This issue will be resolved in an upcoming software release.
2.3 Not all error counters cleared by RESET_ERR_CNTR_CMD (338706)
2.3.1 Description
Whe n using the RESET_ERR_CNTR_CMD parameter or DM 3 PGN - diagnostics data clear of previously active
DTCs to reset the error occurrence counte rs, only the first 29 counters with a value gre ater than zero w ill be
cleare d.
2.3.2 Solutions
Send multiple re quests to clear the error counters b y toggling RESET_ERR_CNTR_CMD or sending the DM 3 message repeatedly. This version of the softw are has 72 occurrence counte rs, so issuing the command three times w ill cle ar all counters.
This issue will be resolved in an upcoming software release.

2.4 PLUS+1® parameter value cannot be changed if its source is not set to 1 (346303)
2.4.1 Description
PLUS+1® p arameters w hich are read/w rite or read-only depending on the setting of the corresponding sourc e parame ter (_SRC) cannot be changed until the source is set to PLUS+1®.
This issue is particularly apparent whe n dow nload ing paramete rs from an XM L file in Service Tool.
2.4.2 Solutions
Ensure that the corresponding source parameter is set to PLUS+1® before writing to the parameter. If downloading an XML file in Service Tool, arrang e the p arameters so that the source paramete r comes earlie r in the list than the parameter.
2.5 Solenoid fault test fails for cylinder A1 (354599)
2.5.1 Description
The solenoid fault te st occasionally fails for cylinder A1 in a healthy system. The e rror only occurs on the first test after pow er-on.
2.5.2 Solutions
Disable the start-up solenoid fault te st by setting EN_STARTUP_SOLENOID_FAULT_TEST to 0.
Run the manual solenoid fault test using EN_MANUAL_SOLENOID_FAULT_TEST twice, disregarding the error states after the first test.
This issue will be resolved in an upcoming software release.
2.6 Pressure sensor invalid low error with sensor connected (361396)
2.6.1 Description
A p ressure sensor invalid low error can be trig gered at low pressure in an e le ctrically noisy environme nt. The following errors may be seen:
Service 1 outlet pressure reading below minimum (SPN 520960, FMI 18) Service 2 outlet pressure reading below minimum (SPN 520961, FMI 18) Service 1 external load-sense pressure reading below minimum (SPN 521020, FMI 18) Service 2 external load-sense pressure reading below minimum (SPN 521021, FMI 18)
2.6.2 Solutions

2.7 Software update fails when using multiple CAN bus devices (400960)
2.7.1 Description
Dow nloading new softw are to the DPC12 controller using the PLUS+1® Se rvice Tool can fail when other CAN bus devices are communicating on the bus.
2.7.2 Solutions

3 Configuring a new controller
The DDP096 is a softw are-driven product and requires initial config uration to operate correctly in a hydraulic system or vehicle. The follow ing items should be considered when setting up the DPC12 controller for the first time. Failure to do so may result in the pump being unab le to ope rate reliably.
If you have any issues or require assistance with the initial setup, please contact your Danfoss representative.
3.1 Use of a CAN Bus
The DDP096 softw are is de signed to be setup and monitored using a CAN bus. It is recommended that a diagnostic connector is available in every installation including a DPC12 controller.
The DDP096 softw are includes an error to detect electrical problems w ith the CAN bus during operation. This error w ill be triggered in a system where no CAN bus is connected to the controller w hile it is operating. To prevent the error being triggered and the pump disabled, the IGNORE_EPV_FLAG parameter must be changed from its default value. See the Communication parame ters and Errors sections for further de tails.
Warning
Parameter IGNORE_EPV_FLAG must be set to 1 if no CAN bus connection is present in operation.
The DPC12 controller must be ab le to be uniquely addressed when using a J1939 CAN bus for control or monitoring. For this it imp le ments the J1939 ad dress claim proced ure. Details of this procedure should be understood as add ress claim errors w ill result in the pump being disabled. See the Address scheme and
Errors sections for further details.
Warning
If more than one DPC12 is connected to the CAN bus the controllers must be uniquely ad dressed.
3.2 Control configuration required
The factory default setting for the DPC12 controller sets the control method to a static displacement of zero output. The DDP096 softw are must be config ured to the control method required b y the hydraulic system or vehicle. Se e the Control configuration section for more de tails.
3.3 Control loop gains
A control loop w ith tuneable gains is used by the software in pressure control and load -sense control mode s. These gains must be tuned to match the hydraulic characteristics of the system and the desire d pump response. It is recommended to undergo training or receive assistance from your Danfoss representative when doing first start-up of a new hydraulic system operating in either of these mod es to ensure that the control loop g ains can be tuned for optimal system p erformance and response.
3.4 PLUS+1® Service Tool
The Danfoss PLUS+1® Service Tool is used to configure the DDP096 software. Service Tool pages are available to make interacting w ith the DDP096 software parameters simple. The Service Tool can be downloaded from
the Danfoss w ebsite . Please contact your Danfoss re presentative for access to the DDP096 Service Tool pages.
3.5 Backup parameters
It is highly advisable to backup the DDP096 software paramete rs once setup is comp le te. In the event of damage to the DPC12 controller or non-volatile memory corruption the backup parameters can be downloaded to a new DPC12 controlle r to allow the DDP096 pump to function as desire d. Please contact your Danfoss rep rese ntative for training on using the PLUS+1® Service Tool to export paramete rs from a DPC12 controller.
Software Manual
Digital Displacement® Pump Software Version 2.7.1
Warning
Danfoss and the PLUS+1® Service Tool do not automatically store copies of DDP096 software parameters. Backups should be made after the configuration is chang ed.

4 Commissioning mode
The DDP096 softw are includes a commissioning mode w hich is used to exercise pumping units when the pump is not in normal operation. More d etail on commissioning a DDP096 pump and DPC12 in a hydraulic system is provided in the Digital Displace ment® Pump Gen 1 DDP096 and DPC12 Te chnical Information.
Warning
Some error protection is disabled in commissioning mod e. The use r should e nsure that the system is properly protected hydraulically (for instance with a pressure relief valve on e ach outlet) and is monitored carefully throughout.
4.1 Entering and exiting commissioning mode
Commissioning mode is ente red by setting the EN_COMMISS parameter to "enabled" (1) and power cycling the controller. The DEVICE_MODE paramete r can be used to check that the DDP096 software is in commissioning mode - the value will be 2 w he n in commissioning mode.
Commissioning mode is left by setting the EN_COMMISS p arameter back to "disabled" (0) and power cycling the controller.
4.2 Commissioning actions
Five actions are available to the user in commissioning mode:
fire pump x1 pump x100 raw displacement, service 1 raw displacement, service 2
Each is described in the following sections.
To set up an action:
1. the COMMISS_ACT_TYPE paramete r should b e set to the value corresponding to the p articular action.
2. the COMMISS_VALUE parameter should be set to the required coil number or displacement p erce ntag e.
3. the COMMISS_CMD parame ter should be set to 1 to start the action.
4. the COMMISS_CMD parame ter should be set back to 0 w hen the action is comple te before starting the next action.
Each action may be disabled due to the current shaft speed or active errors. The DDP096 softw are show s which actions are allowed via the COMMISS_LEVEL parame ter, w hich has three levels:
0. Internal 24V power supply proble m, inc luding no power to coil supply pins, is indicated by the ERR_AE_3599_02_LM_OUT24V error b eing active.
1. At least one severe error active (other than ERR_AE_3599_02_LM_OUT24V).
2. No severe errors active.
Whe n an action is requested, the DDP096 software reports the result of the request with the
COMMISS_STATUS parameter. It shows w hether a request was d enied , due to the COMMISS_LEVEL being
low er than that required for the requested command, and whe ther the action is in prog ress. For fire and pump x1 actions the parameter is set to the in progress value only for a very short time.
4.2.1 Fire
The fire action allows the coil of a p articular pumping unit to be ene rgized. This is intend ed to allow the user to check for correct w iring to the coil, either by listening for the audible click produced during the energization or by using a current probe to view the current in the wire to the coil.
COMMISS_ACT_TYPE is 1 for the fire action and the COMMISS_VALUE paramete r selects the coil to be fire d (see
Coil numbers section).
Software Manual
Digital Displacement® Pump Software Version 2.7.1
The fire action is available whether or not the shaft of the pump is sp inning , and requires the COMMISS_LEVEL to be 1 or 2.
4.2.2 Pump
The pump action e nergizes the coil of a particular pumping unit at the correct shaft angle for pumping, allowing the user to check that fluid is displaced by that pumping unit. This can be used in conjunction w ith a flow meter or pressure sensor/gauge to verify the function of that pumping unit.
The COMMISS_VALUE parameter selects the coil to be fired (see Coil numbers section). A single pumping stroke can b e requeste d using COMMISS_ACT_TYPE 2 and one hundred pumping strokes can be req uested using COMMISS_ACT_TYPE 3.
The pump action is only available when the shaft is sp inning and the minimum pumping speed is reached (see the ERR_AE_520975_17_LM_SHSPD error), and requires COMMISS_LEVEL to be 2.
4.2.3 Raw displacement
The raw displacement action allow s the use r to se t the DDP096 to pump indefinitely at a particular fraction of its availab le flow.
The COMMISS_VALUE parameter sets the displaceme nt fraction, and is scaled the same way as the
DISP_REF_S1 parameter. COMMISS_ACT_TYPE 4 re que sts flow from service 1, and COMMISS_ACT_TYPE 5
requests flow from service 2 (in two-service DDP096 softw are). For two-service operation the selected service config uration is always that correspond ing to index 0 of the SERV_CONF_INDEX parame ter (see the Service
sw itching section).
The raw displacement action is only available w hen the shaft is spinning and the minimum pumping speed is reache d (see the ERR_AE_520975_17_LM_SHSPD error), and req uire s COMMISS_LEVEL to be 2.
4.2.4 Coil numbers
For fire or p ump actions the user must send a particular coil numb er to set the DPC12 coil output w hich is to be actuated.
The map ping betw een pumping units and coil numbers is shown in the follow ing table. Please refe r to the
Dig ital Disp lacement® Pump Gen 1 DDP096 and DPC12 Technical Information for the physical locations of the

5 Control configuration
The DDP096 softw are is able to operate each service (hydraulic output) in one of se veral configurations to provide the required control re sponse . Each service operates independently. The se configurations are controlled by setting the value of the control mode p arameter and the limit source parameters (see Control
mode parameters and Limits paramete rs sections). The application of these different options is detailed in the Dig ital Disp lacement® Pump Gen 1 DDP096 and DPC12 Technical Information. Please contact your Danfoss
representative for further help w ith DDP096 control options.
The configuration must be set-up on each controller after delivery. As the DDP096 is a softw are-controlled prod uct, the same software configuration w ill produce the same control response on all DDP096 and DPC12 hardware in a system w ith the same hyd raulic circuit configuration. For serie s production systems it is recommended to setup the control config uration for the first product and export the paramete r file using the PLUS+1® Service Tool. The same parame ters can then be imp orted and dow nloaded to each subsequent DPC12 controlle r.
5.1 Use cases
Only a sp ecific subset of the available comb inations of control mode, control refe rence source and limit sourc e parame ters are allow ed in this softw are version. These comb inations have been qualified b y Danfoss to ensure the ir correct ope ration. Selection of any other combinations will result in an unsupp orted DD config uration error (SPN 521006, FMI 2). Where the desired comb ination is not included in the list, it is often possible to use another combination w hich include s enabling an additional limit. In this case the maximum limit value can be set and the DDP096 p ump will operate as if the limit had be en se t to "unlimite d".
For the control mode parameters, named CONTROL_MODE_Sx (where x is number of the service the p arameter applies to), the possible values are:
0 - displace ment control 1 - pressure control 2 - load -sense control (LS)
For the refe rence and limit source parameters, named parameter_SRC_Sx (w he re x is number of the service the parameter applies to), the possible values are:
0 - unlimited 1 - PLUS+1® Service Tool 2 - J1939 CAN message
Further information on these parameters can be found in the Service 1 parameters section.

6 Two-service operation
Two-service DDP096 software (file named ML, marked GEN1_AB in Service Tool) is used w ith a DDP096 pump fitte d with a multi-outlet endcap to allow the single pump and controlle r to provide flow to tw o hydraulic circuits. The parame ters for both service 1 (marked _S1) and service 2 (marked _S2) must be configure d suitably for the hyd raulic system or ve hicle.
6.1 Service independence
Each service controlled by the DDP096 software acts as an independe nt flow source.
Any coordination between the tw o services, for instance a whole-pump torque limit, must be calculated b y a system controller and communicated to the pump as a control reference or limit per service.
6.2 Service switching
Service switching, also known as dynamic g anging, allows the allocation of some of the pumping units of the pump to be switched from one control service to anothe r unde r the command of a system controller. The DPC12 controlle r does not control the external valves or other hydraulic equipment needed to connect the correct outlet ports of the DDP096 pump, this must be considered in the system controller design.
Warning
The physical hydraulic connections of the relevant output ports of the DDP096 pump must match the service config uration selected. Mismatch could result in unintended flow to a particular service.
The twelve pumping units in the machine are group ed into four indepe nde nt groups, each consisting of three interconnected pumping units. These groups are know n as "pump lets". An example of how the pumple ts, pump ing units and outlet ports relate is shown below. Please refer to the Digital Displace ment® Pump Gen 1

The service switching feature is controlled by supplying a config uration inde x (SERV_CONF_INDEX) to select the active combination of pumplets assigned to the service . This index can be set statically in the PLUS+1® Service Tool or commanded dynamically by a system controller over J1939. The following tab le describes the pump let-to-service assignment for each available configuration:
Index Service 1 Service 2 No tes
0 1+3 2, 4
1 1+3 4 There is no flow from pumplet 2
2 1+3, 2 4
The service configuration can be change d w hile the pump is in operation. When command ing a service , the flow, torque and power limit sig nals always re late to the real hydraulic output of the service. The displace ment re ference is a fraction of the disp lacement available from the pumping units currently assigned to a service; the available disp lacement may change as the service config uration is changed.
Warning
There will be a change in flow for a given displacement re ference command when the se rvice config uration is changed under disp lacement control.

8 Errors
The DDP096 softw are contains an error-handling system w hich is d esigned to protect the pump and system from undesirable be havior when there is an error de tected w ith the software, communications, DPC12 hardware, sensors or DDP096 pump.
The e rror handling system consists of a number of errors (see Error list section) each of which has a severity which governs the error handler's response when the error is detecte d. The effect of each severity is:
Info: no effect on operation. Warning: normal operation stopped. error ig nored in disable d state (when SUPPORT_DM13_PGN parame ter is enabled). Critical: normal operation stoppe d. Severe: normal operation stoppe d. Fault state cannot be reset by DM 11 message.
Two me chanisms e xist to return the controlle r to an active state following a fault - the J1939 DM11 message (see DM 11 PGN - diagnostics data clear of active DTCs section) or power-cycling the DPC12 controller.
Active and previously active errors can be read over CAN bus using standard J1939 me chanisms (see DM1
PGN - active diagnostic trouble codes and DM 2 PGN - previously active diagnostics trouble codes sections) or
by using the PLUS+1® Se rvice Tool to read the associated parameters. The PLUS+1® Service Tool can also display counters for the numbe r of times each error has occurred since the last error counter reset (via the DM3 messag e, se e DM3 PGN - diagnostics d ata clear of p reviously active DTCs section, or
RESET_ERR_CNTR_CMD paramete r).
8.1 Error handler states
The e rror handler component op erates as a state machine for the w hole DDP096 software. The states are explained in the table below.
State DEVICE_STATE code Descriptio n
Initialization 0 Start-up state
Disabled 1 Software is held in this state until reception of DM13 message if SUPPORT_DM13_PGN parameter is enabled.
Active 2 Normal operation
Fault 3 There is an active fault of severity warning, critical or severe, or there was previously a severe fault. Pump does not operate.
Fault hold 4 All previous faults non-severe faults have been cleared, but software remains inactive until reception of DM11 message.
The transitions be tween states are show n in the flowchart below .

8.3 Diagnosing faults
The following me thods can be used to diagnose a fault in the DDP096 pump and software:
View the Diagnostic LED color to establish the current status of the software. Use the J1939 DM 1 and DM2 messages to ide ntify the active and previously active errors (see DM1 PGN
- active diag nostic trouble cod es and DM2 PGN - previously active diagnostics trouble codes sections).
In the PLUS+1® Service Tool:
check the DEVICE_MODE and DEVICE_STATE parameters to establish the current status of the softw are. check the currently active errors using the e rrors status pag e (or the active error parameters dire ctly). check the previously active errors using the counters on the error status page (or the error counter parame ters directly). use Commissioning mod e to allow limited operation with some errors active to diagnose system
issue s. Follow the steps in the Commissioning and troubleshooting section of the Digital Displace ment® Pump

9 J1939 CAN protocol
The DDP096 softw are on the DPC12 can be commanded dynamically during use w ith a system controller, testing application or other CAN bus-capable device. The softw are also reports the current operating status and its error signals over the bus.
The protocol used is based on the automotive SAE J1939 protocol which is transmitted over a standard CAN bus connection. This manual does not aim to describe all of the features of J1939. How eve r, it is possible to control the p ump by sending standard CAN frames (w ith 29-b it IDs) formatted to match the J1939 protocol implementation. Ple ase refer to SAE publications or contact your Danfoss rep rese ntative for further advice.
Two important concepts for the transmission and recep tion of J1939 messaged are Paramete r Group Numbers (PGNs), which identify the purpose and format of a particular message containing data, and Suspe ct Parameter Numbers (SPNs), w hich identify particular sig nals or parameters contained within a message. The J1939 standard specifies many PGNs and SPNs and le aves space for manufacturers to spe cify the ir own when neede d. The standard also uses the term Diag nostic Trouble Codes (DTCs), which represent an error in the system.
CAN messages are limited to eight data bytes. When data longer than this is sent, a multi-packet message is sent using a mechanism defined in the J1939 stand ard. Typically the DDP096 software uses a Broadcast Announce M essage (BAM) session when required.
9.1 Address scheme
Each device on a J1939 netw ork must be uniquely ad dressable to be able to send and receive message s. This is achieved through use of a J1939 Name to uniquely identify the function of a device on the network and an addre ss give n to each device which is used during the communications.
The fields of the J1939 Name assigned to the controller are show n in the table below .
J193 9 Name field Length ( bits) V alue
Arbitrary address bit 1 0
Industry group 3 3
Vehicle system instance 4 0
Vehicle system 7 0
Function 8 255
Function instance 5 Set by FUN_ECU_INSTANCE
ECU instance 3 Set by FUN_ECU_INSTANCE
Manufacturer code 11 57
Identity number 21 200200
Whe n using more than one DPC12 controller on the ne twork, a unique FUN_ECU_INSTANCE value must be assig ned to each controller in order to ensure that each device has a unique J1939 Name and can therefore be assigned an address on the J1939 netw ork.
FUN_ECU_INSTANCE: This parameter sets the ECU Instance and Function Instance values which form p art
of the J1939 Name of the device, allowing the use r to give each d evice a unique name in the system. Any value which is not shared with another DPC12 controller will allow the system to operate correctly.
Bit No. V alue/ran ge Descr iption
3 bits 0..2 0..7 ECU Instance
5 bits 3..7 0..31 Functional Instance
A g roup of controllers are often required to perform a specific function in a system. In comp le x systems, the same function may be implemented more than once. To identify which instance of a function a particular controller belong s to, the Functional Instance is used. The ECU Instance is used to identify a particular controller within an instance of a function. Conside r, for example, a braking system which has two controllers ­each controller would have a different ECU Instance , but the same Functional Instance as b oth controllers are required to perform the braking function. Now, consider that this brake syste m is replicated on each wheel of
Software Manual
Digital Displacement® Pump Software Version 2.7.1
a vehicle - the controllers on each wheel would be able to keep their existing ECU Instance values, how ever the Functional Instance values w ould have to be unique to each w heel.
NODE_ID: This parameter sets the address w hich the DPC12 controller will attempt to claim on start-up.
This value must not be in use by any other DPC12 controller, and should also not be used b y any other device on the bus. Note this parameter is also used by the PLUS+1® Se rvice Tool to identify the DPC12 controller.
On start-up the DPC12 controller will initiate an add ress claim procedure where it attempts to claim the addre ss configured by the NODE_ID parame ter. The re sult of the claim proced ure w ill be one of the follow ing:
The address is claimed successfully and the controlle r starts communication. The address cannot be claimed because a device with a higher-priority J1939 Name has claimed this addre ss. An address claim failure error will be raised. Another device on the network with the same J1939 Name is d etected, usually another DPC12 with the same value of the FUN_ECU_INSTANCE parameter. A name conflict error will be raised.
An outline of this procedure is show n in this flowchart:

9.2 PGN priorities
The three-bit priority field in J1939 is inte nde d to give the syste m d esigner the ability to prioritize messages on the bus, with a lower number giving the message a highe r p riority. In the current implementation the messages received by the DPC12 controller w ill only be read correctly if a spe cific priority (3) is used. This be havior w ill be changed in a future softw are upd ate to give fle xibility in the p riorities used.
All received J1939 priorities must match the me ssage information table to b e received correctly.
9.3 SLOTs
J1939 uses standard SLOTs (scaling, limit, offset and transfer function) to represent physical quantitie s as data in the J1939 CAN frames. As well as using standard SLOTs, the DDP096 softw are uses several custom SLOTs where a standard SLOT w as not available. These SLOTs are named with a DD prefix. Details of e ach SLOT used in the softw are are given in the table be low. Full details can be found in the J1939 Digital Anne x, available
from the SAE.

Whe re a SLOT used in J1939 communication has highe r resolution than the correspond ing PLUS+1® Service Tool paramete r, the value will be truncated (rounded-down) to match the parameter resolution. If a differe nt rounding method is desired the system controller code should include the rounding to the parameter's precision before sending the value over J1939. This behavior w ill b e changed in a future softw are update to allow the full resolution of the SLOTs to be used for more precise control.
9.4 Diagnostic messages
Several stand ard J1939 diagnostic me ssag es are implemente d in the controller.
Each diagnostic messag e is detailed in the following sections. Example sequences of J1939 message frames in diffe rent circumstances are given for each diagnostic messag e.
In all example me ssage id entifiers ("msg ID"s) the system controller node ID in hexad ecimal is indicate d by yy and the DPC12 node ID is indicated by zz. Following the J1939 standard, the destination addre ss for any message can be set to 0xFF rather than a specific DPC12 node ID to send a messag e to all node s in the system.
9.4.1 DM1 PGN - active diagnostic trouble codes
The DM1 PGN communicates the details of the errors (DTCs) which are curre ntly active in the DDP096 softw are.
If more than one e rror is active, a BAM session is use d to communicate the active errors. The maximum number of errors that can be sent by BAM session is 30. If there are 29 active errors at the same time, the "Too many errors to handle by J1939" error is automatically raised, w hich is the 30th error in the BAM session.

Enab ling the SUPPORT_DM13_PGN parameter w ill cause the DPC12 to ignore all info and warning severity errors, not communicate them on the CAN b us, and kee p the DPC12 in the disabled state (and therefore not provide flow) afte r the controller is pow ere d on until it re ceive s the DM13 message from a system controller. Whe n the parameter is disabled the DPC12 transitions immediately to the active state unless there are any non-info le vel errors, in which case a fault w ill b e declared immediately.
If parame ter SUPPORT_DM13_PGN is set to 1, after pow er-on the DPC12 w ill process only critical and severe active errors and communicate the m on the CAN bus. Active info and w arning errors w ill be ignored. After receiving 'Start Diagnostic DM13' the DPC12 will return to normal error hand ling state and communicate all

If parame ter SUPPORT_DM13_PGN is set to 0, the DPC12 will send a negative acknowledgment, see the
Acknowledgme nt PGN section. All active errors will be processed and communicated on the CAN bus as

10 Updating software on the controller
The softw are on the DPC12 controller can be updated in the field by using the PLUS+1® Se rvice Tool. Ple ase refe r to the PLUS+1® Service Tool manual for instructions on this process.
Ple ase read the relevant release notes before upd ating the software. Systems should be recommissioned after updating to ensure the DDP096 pump functions as desired.
The parameters on the DPC12 controller should be backed up before upgrading the softw are. If the software is upgraded to a version w ith new parameters the non-volatile memory format may be incompatible and the parame ters reset to the ir default value. Please check all parameters after the update has been completed.
Warning
Parameters may be reset to default during a softw are upd ate.
