X10XX01X1100XXXX

This allows to define a filter for the bus statistics of the data frames and the bus load at the layer 2 level. It has an effect on the 1st and 2nd bytes of the CAN message (COB ID). In the CANopen protocol the CAN identifier is set up as follows:

1st byte:

bit ‘F’	bit ‘E’	bit ‘D’	bit ‘C’	bit ‘B’	bit ‘A’	bit ‘9’	bit ‘8’
CANopen Function Code most significant 4 bits of the node ID

2nd byte:

bit '7'	bit '6'	bit '5'	bit '4'	bit '3'	bit '2'	bit '1'	bit '0'
least significant 3 bits of the node ID RTR bit data length (DLC)

The "Frame Filter" indicates which bits of the 1st and 2nd bytes of the CAN identifier are to be set (bit = 1), to be reset (bit = 0) or are not to be considered (bit = X) so that the message can pass the filter thus being considered for the bus statistics. With the keys 0 - 9 or A - F the individual bits of the 16-bit mask can be changed. With the key "ENTER" the bus statistics are indicated by using the entered filter.

2.2. Menu Node Config.

Specially for the non programmable bus modules with CANopen capabilities from ifm electronic some device parameters must be set before using the modules. The parameters are the node number (node ID) and the baud rate. The valid default setting is specified in the data sheets of the devices.

Also, the module configuration can be changed. A module connection can for example be configured as a digital output or an analog input. The possible settings are stated in the data sheets of the devices.

To avoid conflicts with the node configuration only one module should be connected to the CAN analyser. Since with some settings the CAN analyser performs master services no other network master (e.g. ecomat R 360) must be active.

The indicated data are updated every 200 ms via RTR message requests.

2.3.3. Menu Trace

F1 Trigger: AUTO

F2 RecTele: 0000

F3 _Start, *Stop

F4 Send Buffer

F1 Trigger: AUTO Display of the current trigger mode. By pressing F1 the trigger mode and the trigger conditions can be changed (=> menu "Trigger").

F2 RecTele: 0000 By pressing F2 it is possible to look at the messages transferred via the bus. The number of the received messages is shown right-aligned.

Since the buffer can only contain 1024 messages the first messages are overwritten by current messages if this number is exceeded.

F3 _Start, *Stop Starts or stops writing current messages transferred via the bus into the buffer. If the trigger type is not set to "AUTO", starting or stopping the writing into the buffer depends on the occurrence of the trigger condition according to the selected trigger type. "*" before "_Start" or "_Stop" indicates the current state "Reception" or "Reception stopped". "!" at the end of the 4th display line (after "F4 Send Buffer") indicates that the bus transmission is disturbed (error frames received).

F4 Send Buffer Sends the contents of the buffer to the CAN bus. This is done to transfer and further process the traced messages, e.g. to an external PC.

Menu Trigger

F1 Trigger: AUTO

F2 COBI-IDs:

181,194,201,701

F1 Trigger: AUTO Selection of the trigger type (=> menu "Trigger type").

F2 COB-IDs Input of maximum four CAN COB IDs whose messages release triggering or "FFF" for all IDs (3 digits, hexadecimal, 11 bits).

Menu Trigger Type

F1 Auto

F2 Pre-trigger

F3 Mid-trigger

F4 Post-trigger

F1 Auto Triggering is released by no message. The cyclical writing of current messages into the buffer starts by pressing "*Start" in the menu "Trace" and stops by pressing "*Stop" in the menu "Trace".

F2 Pre-Trigger Current messages are continuously and cyclically written into the buffer by pressing "*Start" in the menu "Trace". When the trigger condition is met or by pressing "*Stop" in the menu "Trace" the reception stops.

F3 Mid-Trigger Current messages are continuously and cyclically written into the buffer by pressing "*Start" in the menu "Trace". When the trigger condition is met writing new messages into the buffer continues until half the buffer is overwritten or by pressing "*Stop" in the menu "Trace".

F4 Post-Trigger Writing current messages into the buffer only starts when the trigger condition is met and "*Start" in the menu "Trace" has been pressed. Writing into the buffer continues until the whole buffer is full or by pressing "*Stop" in the menu "Trace".

Menu RecTele: 0000

F1 Selective Only certain message types with certain COB IDs are displayed (=> menu "Selective Read").

F2 All Telegrams All messages are displayed (=> display "Messages").

Menu Selective Read

Filt. COB-IDs:

181 194 201 701

COB-IDs: Input of max. four CAN COB IDs whose messages are to be displayed or "FFF" for messages of all IDs (3 digits, hexadecimal, 11 bits)

Display of messages

All messages in the buffer or the messages in the buffer selected in the menu "Selective Read" are displayed in plain language. With the selected trigger type "Auto" the first message in the buffer is indicated. With all other trigger types the first message displayed is the one in the buffer which released triggering.

The keys ↑ and ↓ enable scrolling through the buffer contents. With Home and End you can jump to the beginning and the end of the buffer contents.

The first three characters of the message display are the CAN COB ID (3 digits, hexadecimal, 11 bits) of the message. Then come the data of the message in hexadecimal format.

With the T key the time stamp for the messages can be indicated (toggle). The display is in 4 digits in decimal format in steps of 1 ms starting after "F3 *Start" has been pressed (e.g.: 012 90 FF T:0732).

Examples of how the messages are represented on the display:

181 AB CD EF

194 FF DD CC BB

77 88 99 12

--- RTR-Telegram

With RTR messages the COB ID cannot be indicated. Owing to the characteristics of the Intel 82C527 "--- RTR-Telegram" is always displayed.

2.3.4 Menu Bus-Statistics

Bus-Statistics:

F1 Selective

F2 All Frames

F1 Selective Selection of certain message frames via "Acceptance Mask" and "Acceptance Code" (=> menu "Selective").

F2 All Frames Display of the bus statistics for all message frame types (=> menu "All Frames").

X10XX01X1100XXXX

This allows to define a filter for the bus statistics of the data frames and the bus load at the layer 2 level. It has an effect on the 1st and 2nd bytes of the CAN message (COB ID). In the CANopen protocol the CAN identifier is set up as follows:

1st byte:

bit ‘F’	bit ‘E’	bit ‘D’	bit ‘C’	bit ‘B’	bit ‘A’	bit ‘9’	bit ‘8’
most significant 8 bits of the COB ID

2nd byte:

bit '7'	bit '6'	bit '5'	bit '4'	bit '3'	bit '2'	bit '1'	bit '0'
least significant 3 bits of the COB ID RTR bit data length (DLC)

The "Frame Filter" indicates which bits of the 1st and 2nd bytes of the CAN identifier are to be set (bit = 1), to be reset (bit = 0) or are not to be considered (bit = X) so that the message can pass the filter thus being considered for the bus statistics.

With the keys 0-9 or A-F the individual bits of the 16-bit mask can be changed.

With the key "ENTER" the bus statistics are indicated by using the entered filter.

Menu All Frames

Error Display of the number of the error frames per s and their total number.

Overl Display of the number of the overload frames per s and their total number.

Busld Display of the bus load in % per s and the total bus load in %.

With the key "0" all values can be reset to zero. If a value becomes greater than "9999", "OvFl" (overflow) is indicated.

2.4. Menu Baudrate

F1 1M F5 100k

F2 500k F6 50k

F3 250k F7 20k

F4 125k F8 AUTO

After power on the default baud rate is 125 Kbits/s.

With the keys F1 to F7 the requested baud rate can be selected.

F8 AUTO automatically determines the baud rate of the connected modules or of the CAN network in the range of 1 Mbits/s to 10Kbits/s. The "Scan" operation does not stop before the baud rate is clearly detected.
