3 C400 controller summary Limitations HMIs Room units Notes: KNX based HMIs and room units cannot be connected to the controllers since C400 controllers do not support the peripheral bus. 3.5 Limitations C400 controllers are designed for residential and light commercial applications requiring less performance, consider the following limitations when programming applications. Detailed information can be found in the Climatix limits document.
C400 controller summary Limitations 3 3.5.1 Special function list Major items different from POL600 are listed below. A6V1127616_en--_a Item Description RTC (Real Time Clock) As POL461.45/STD does not have a battery, the RTC will be reset to default settings upon power failure. Functions related to RTC, such as trend, archive and alarm history cannot be fully supported. You need to re-adjust the clock upon power failure to support these functions.

The modulation can be measured between Process error 0 and 200. A value of 200 equals 100% switch-on time and a value of 0 is equal to 0% switch-on time. 0 … 200 I-PWM >500 Hz The measurable frequency is 20 ... 500 Hz. Below 20 Hz, the input is handled as a normal digital input.

(0 is equal to 0% switchon time, 200 is equal to 100% switch-on time.) Notes on EMC measures: ● ● Use shielded twisted pair cable for each single PWM output. Connect the shielding directly to the largest possible surface area of protective ground. 4.
4 Hardware IO connection Relay outputs For POL461, the rated current for Q2 and Q3 is 3 A. use a 6.3 A fuse to protect the controller from overheating. For POL467 and POL468, the rated current for Q2 and Q3 is 5 A and is designed to withstand high inrush current (7 to10 times of the rated current, for example capacity load 40 A (100 us) ). As a result, terminals Q2 and Q3 on POL467/468 can drive high efficiency devices such as a pump or compressor within the specified rated current range.
Hardware IO connection 4 EEV interface (stepper motor drive/PWM) 4.9 EEV interface (stepper motor drive/PWM) Use The unipolar motor outputs (only for POL461.45/STD and POL468.65/STD) are used for unipolar stepper motors in full or half step mode. Connection example The following illustration shows examples of the position and identification of the unipolar motor output connection. The interface supports 5 or 6 wires. The difference is whether the wires are connected to 2 coms or 1 com.

Programming and commissioning 5 Programming tool: SAPRO 5 Programming and commissioning The C400 controllers are based on the Climatix tools platform for programming and commissioning. 5.1 Programming tool: SAPRO SAPRO is a programming tool for creating and maintaining Climatix controller applications. C400 controllers require Climatix VVS11 or higher. Some specifics related to the C400 controllers are described in this chapter. Refer to SAPRO help and programming guide for details. 5.1.
5 Programming and commissioning Programming tool: SAPRO ● Watch page implementation for accessing the controller via Smart HMI and Climatix IC ● HMI implementation for HMI-TM Refer to the “Basic Template user documentation” for more details Migrating from a legacy controller Consider the following when migrating an application from a legacy controller (POL400 / 600). ● Hardware IO mix: Evaluate ways to migrate hardware IO mix including extension IO modules since C400 only supports 1 extension module.
Programming and commissioning 5 Programming tool: SAPRO Lifecycle of flash for ApplicationSave After ApplicationSave is triggered, all object parameters are written into the flash. Consider the flash’s lifecycle*) when triggering ApplicationSave. *）An entire flash chip typically has 100,000 erase/program cycles. As a consequence the times for ApplicationSave and the chip’s lifecycle must be balanced. The graph below shows a typical lifecycle with different ApplicationSave scenarios.
5 Programming and commissioning Programming tool: SAPRO ● Strategy 3: ApplicationSave depends on the COV (change of value) of any object member. The function block DB_ApSave_MbrChg pre-installed in the basic template, can implement this strategy. Note: Applying this strategy to counter-type objects may trigger too many write cycles. We recommend a trigger with timer. ● Strategy 4: ApplicationSave can be scheduled by timer in the application using block SysCtl_ApSave available in the xLibCAS\Universal\Sy
Programming and commissioning Commissioning tool-Scope 5 Use SCOPE to verify whether the hardware IO configuration is properly initialized after restarting the controller. If you see a ConfigErr (as shown in the picture above), there is a mismatch of the programmed and loaded IO configuration. In this case, restart the controller. 5.2 Commissioning tool-Scope What is Scope Scope is a commissioning and service tool for Climatix controllers and operation units (HMI).
