CA340 and CA541

Process value and parameter indicators for CAN-Bus

Product Features:

 The CA340 variant is a simple indicator unit for remote display of all actual data which

are available on the connected CAN-Bus network. Arbitrary parameters or actual values

can be read or displayed.

 CA541 is a combination of preset switch and indicator. While the BCD switch allows to

make register changes via CAN-Bus, the LED display provides information about the

actual setting of the same or any other register value.

Available Devices:

 CA340: Display unit only

 CA541: Display / Preset combination (SDO / PDO switchable)

1.3. Installation The device is only allowed to be installed and operated within the permissible temperature range. Please ensure an adequate ventilation and avoid all direct contact between the device and hot or aggressive gases and liquids. Before installation or maintenance, the unit must be disconnected from all voltage-sources. Further it must be ensured that no danger can arise by touching the disconnected voltagesources.

2. Introduction The CA340/541 display units have been designed to display single parameters or registers (like position or speed) in systems using a CANopen network for communication. CA541 also allows remote setting of a single parameter.  CA340 serves as pure readout unit without preset functions. Both units are built into a DIN housing and have a 6 decade, 15mm size LED-display.  CA541 additionally includes a 6 digit BCD thumbwheel switch (Preset range 0...999 999).

Slider 4 defines the most significant digit of the front thumbwheel switches to be transmitted as a number or a sign (CA541 only): ON ON 1234 OFF 1234 OFF OFF: 0...9 ON: +/- The version with a sign (option VZ000) requires slider 4 to be “ON“ at any time! 6. Setting of unit address and transmission mode Sliders 1-5 of the 8-position DIL switch select the unit address (01-31). Slider 8 determines the CANopen transmission mode: Set to OFF, data is transmitted by SDO (Service Data Object, see chapter 7).
PAGE 9
7. Data transmission by SDO (Service Data Object) [DIL switch slider 8 = OFF] The unit requests the display value by an SDO (Service Data Object) read request and transmits the preset value (CA541 only) by an SDO write request. Within the next 2.5 sec (Timeout) a corresponding read or write response is awaited. The unit operates similar to a CANopen master (But it is not a master!). There-fore, the selected unit address must match with the target device.
PAGE 10
The code of the register to be displayed and the code of the register to be Set are requested from register code 473 of the target unit. When transmitting on parameter channel 1 (SDO1) Subcode 3...6 is used, transmitting on parameter channel 2 (SDO2) Subcode 7...10 is used. Therefore, it is possible to display respectively to preset two different values of one target device by using two display units running on different parameter channels (Version CA34002A and later).
PAGE 11
With the CA541, Position 6 of the 8-position DIL switch selects only temporary use of transmit data in the target device (no storage to EEPROM), or continuous use even after power down (nonvolatile storage to EEPROM by setting register Code C003 “Par. Save” to 1 after transmitting the value).

Decimal Place: If required, a decimal point can be set by SDO with index 5100hex / Subindex 0 (number of decimal places). However, the value will not be stored to non-volatile memory. Therefore the number of decimal places must be re-set on every power on. Node Guarding: The CA340/CA541 provides CANopen Node Guarding. By this function the master can supervise the unit and detect any device breakdown.
