1 General

1.1 Interface hardware

To communicate with a host computer, an SPS, etc., the controllers R2600 / 01 must be equipped with marking F1. In this case, the controllers are equipped with a serial interface having the following data:
Level types RS-232 and RS-485 (two-wire)
Baud rate 9600 bd
Character format 8 data bits, 1 parity bit, 1 stop bit
Parity Even
Maximum number of equipment on the bus: 32
With RS-485 bus operation, each connected R2600/01 must
have a different interface address (Addr = 0 ... 250) (see operating instructions 3-348-778-15).

1.2 Communications protocol

The transmission protocol used complies with DIN draft 19244. The R2600 / 01 uses only a partial amount of the defined functions which are described below.

1.3 How to connect the interface

1.3.1 RS-232 connection
When using the a RS-232 interface, only one R2600/01 can be connected to a master (e.g. PC), for example, for pre-loading the unit with user-specific data.

1.3.2 RS-485 connection
When using a RS-485 interface, as many as 32 equipment (R2600/01 and others) can be connected to the bus. Thereby, all terminals A, B and/or C are interconnected in parallel. The wiring must be made from equipment to equipment and must not be a star con­nection. With longer bus lines (longer than about 5 m) the bus should be terminated at both ends with the characteristic impedance (e.g. 200 Ω between A and B).
Master R2600/01 R2600/01
A 21 21 B 20 20 C 19 19
When using the 1799-V5040 interface converter on the master, the following pins are connected on the Sub-D plug:
A = 3 B = 8 C = 5

1.4 Principal function

Involved is a master/slave protocol with a fixedly assigned master (e.g. SPS) and as many as 255 slaves (equipment e.g. R2600/01). Communication is in half-duplex mode. An equipment connected to the master becomes active (responds) only, when – it receives a valid telegram addressed to itself and – the minimum specified response delay time (t
av) has elapsed so that the host computer has time to get ready to receive data.
Following, the master may only become active again, when – it receives a reply telegram from the addressed equipment and the specified wait time after a reply telegram (t aw) has elapsed, or – the maximum specified response delay time (t
av) has elapsed.
Within a telegram, pauses of limited duration (t zv = character delay time) may occur between 2 character transmissions.

2 Telegram structure

All telegrams consist of one of 3 sets in both request and reply direction, they differ in their principal structure. Their use is fixed for each interface function of the R2600/01. Structure and use of the set types are described as follows.

2.1 Short set

Short sets are used on the request side (from the master)
for transmission of short instructions to the equipment (e.g. Reset)
for short requests of important data from the equipment (e.g. event data)
Short sets are used on the reply side (from the R2600/01)
for acknowledgement of requests that require no reply data.

2.2 Control set

The R2600/01 uses control sets on the request side only. They serve to request all equipment data that cannot be requested via a short set because a detailed specification is required for them.

2.4 Function and value range of the format characters

2.4.1 Equipment address
0 ... 250 Range for individual equipment addresses = interface address Addr
255 All equipment connected to a bus can simultaneously be addressed under this address. Data and instructions entered with this address
are accepted by all equipment, but there is no acknowledgement made to the master.
2.4.2 Function field (FF)
The function field contains
with the short set the proper user information, predefined by bits and different in request and response direction
with the control and long set the direction and control information for the transmitted data block

Request telegram incorrect
One or more errors occurred, request error status for exact identification!
2.4.3 Parameter index (PI)
The type of the data to be transmitted is defined via the parameter index. The "PI" character is interpreted as follows:
Bit 7-4 Bit 3-0
0 ... Fh 0 ... Fh Selection number for main parameter group Selection number for a special parameter in the main group
Functionally used data and/or setting parameters of an equipment are combined in the main parameter groups. Only those parameter indices docu­mented in section 4 can be addressed in the R2600/01, an error message is issued for all others.
2.4.4 Length and format of the data block
Length and format of the data block are variable and a function of PI and FF. The transmitted values can have byte or word format:
8 Bit
± 7 Bit 2's complement presentation
16 Bit LS byte first ± 15 Bit LS byte first, 2's complement presentation 8/16 Bit LS byte first

2.5 Criteria for the validity of a request telegram

The R2600/01 checks the characters of the telegrams received in accordance with the following tables:
For short set: For control and long set:
Character No. Criterion Character No. Criterion
1 10h 1 68h 2 Interface address Addr or 255 (see 2.4.2) 2 Note length for PS and end character 3 FF = valid function coding 3 Character 3 = character 2 4 PS = Addr or 255 + FF 4 68h 5 16h 5 Interface address Addr or 255
6 FF = 69h oder 89h 7 PI = valid parameter index (see section 4)
. . . (data block) Length + 5 Length + 6 16h
1) Bytewise sum without overflow over all characters from equipment address (Addr or 255) to checksum exclusive
If incorrect values are received for FF, PI and PS, the R2600/01 responds with a short set with set transmission error bit. If the user data is entered beyond its specific value ranges, the R2600/01 responds with a short set with set service request bit. The bit "impermissible value" is set in the error status word 2. If there are other deviations or a parity error, the telegram is invalid, the R2600/01 does not respond.

3.3 Request for cycle data

You will get the most important measuring and output values of the controller in one data package. Cyclic requests of these values are thus made possible in compact form (short set request.
Example: Equipment address = 2
Request from master (short set):

3.4 Request for event data

The event date, combined in 2 words, contain all error messages and alarms of the equipment. They can be called up via short set to identify a special error. This request can be made asynchronous, for example, if the service request bit (collected errors) was set before in any random response telegram in the function field (FF).
Example: Equipment address = 5
Request from master (short set):
R2600/01 response (long set, see 2.3):
See 2.4.2.2 for contents of the function field (FF)
The 4 characters of the event data block are bit fields which are combined to form the error status words 1 and 2. These 4 characters can also be read by data request with parameter index 21h. See the operating instructions for more explanations and information on error elimination.

3.5 Request data from R2600/01

This communication makes it possible to request all values, parameters, configurations, states and equipment markings. Thereby, the data is individually addressed per parameter index. See section 4 for the complete list of all parameter indices.
3.5.1 Request an equipment specification
The parameter index lies between 30h and 3Fh. Thus the characters "from/to channel" and "receipt No." in the control and long set are omitted.
Example: Request for equipment marking having the address = 33 = 21h (see 4.4)
Request from master (control set, see 2.2):

See 2.4.2.2 for the contents of the function field (FF). The "data block" consists of a character 26h as marking for the R2600/01 (see 4.4).
3.5.2 Request for a temperature parameter, for example
The parameter index is not 3xh, thus the characters "from/to channel" and "receipt No." = 1, 1, 0 are contained in the control and long set.
Example: Request for the maximum selectable set point (SP H ) of the R2600/01 with address = 33 = 21h (see 4.1)
Request from master (control set, see 2.2):

3.6 Send data to R2600/01

This communication makes it possible to set all parameters, configurations and operating states which can be changed via operation. Thereby, the data is individually addressed per parameter index. See section 4 for the complete list of all parameter indices. There is no protection against overwriting. The settings of the DIP switches for disabling of the configuration and/or parameter setting are of no importance. Also the start of optimizing cannot be disabled. The R2600/01 checks the transmitted value for its setting range. Should it be beyond its permissible range, it is not stored, the bit "impermissible value" is set in error status word 1, and the "service request" bit is set in the acknowledgement short set. Same as with manual operation of the equipment, it must be noted, that a complete configuration must be made before parameters are set: That is, the "control instructions" and "equipment specifications" must first be transmitted which influence the presentation of the "temperature parameters" (see
4.3 and 4.4).
3.6.1 Sending an equipment specification
The parameter index lies between 30h and 3Fh. Thus the characters "from/to channel" and "receipt No." are omitted in the long set.
Example: Setting the thermocouple type "K" on the equipment having the address = 0 (see 4.4).

3.6.2 Send a control parameter, for example
The parameter index (PI) is not 3xh, thus the characters "from/to channel" and "receipt No." = 1, 1, 0 are contained in the long set.
Example: Send the Heat proportional band Pb I = 2.3% to R2600/01 with the address = 1 (see 4.2).

4 Parameter indices of the equipment parameters

For a request and/or transmission of data from and/or to the R2600/01, not only the parameter index for the individual data but also the format and thus the length of the data block in the long set are of interest. From the column "Format" of the parameter tables and section 2.4.4, the number, order and contents of the characters of the data block can be found. See the operating instructions for detailed information on the function of the data.

4.1 Temperature parameters

The temperature parameters are combined in the main parameter group 0. In the R2600/01, they are stored in standardized form to the measuring range so that other values result when the sensor type or the unit of measure is re-configured, or when a change is made from fixed value or slave controller to differential controller.

4.1.2 Unit of the temperature parameters
The unit of the temperature parameters depends upon – the range marking B1 ... B5 of the equipment (see PI = 33h), – the configured sensor type (see PI = 33h) and – the configured unit of the sensor (see PI = 32h).
Marking
B1, B3, B4 1°C / 1°F 0.1°C / 0.1°F B2, B5 1, 0.1, 0.01, 0.001
With standard signal (B2, B5) and Pt100 with 0.1° display, the decimal point only serves for the display on the R26900/01, not for the parameter val­ues. That is, a value of 234.5 in the display, for example, is to be transmitted as 2345 = 0929. The two characters of the data block then are 29h, 09h.

5 Storage operations

To store all parameter and configuration data of an equipment, it is not required to address all data individually via parameter indices. It is possible instead to directly read and/or write all data stored in the non-volatile data memory (EEPROM) in one record. This function serves to save the data, to quickly load or duplicate user-specific settings to the R2600/01. Length and format of the data block depends upon the EEPROM allocation which can change with the software version of the R2600/01. That is why no information is given about it. Loading of a record to the R2600/01 can, therefore, only be made for the same software version.

5.1 Request a record

Make the request as described in 3.5, the parameter index = D8h.
Example: Equipment address = 4
Request from master (control set, see 2.2):
68h 06h 06h 68h 04h 89h D8h 01h 01h 00h 67h 16h
FF PI PS
Response from R2600/01 (long set):
68h L + 6 L + 6 68h 04h „FF“ D8h 01h 01h 18h Data block „PS“ 16h
PI
Software version
L character

5.2 Send a record

The long set for sending to the R2600/01 can practically only be generated from the received long set at the request of a record. The function field (6th character) in 69h (write data) must be changed for that purpose. When copying to another R2600/01, the equipment address must be adapted (5th character). Following, the checksum (last but one character) must be corrected.
Send from master (control set, e.g. equipment address = 4):
68h L + 6 L + 6 68h 04h 69h D8h 01h 01h 18h Data block „PS“ 16h
FF PI
Reply from R2600/01 (short set):
10h 04h „FF“ „FF“ + 4 16h
The record will only be accepted by the equipment, when the software version (12th character) and the length of the data block agree with the equip­ment. The content of the data block is not checked as it is correct in itself when it comes from a R2600/01. It must be noted to send a record only to an equipment having the same A and B markings as the equipment from which the record comes. If this is not observed (e.g. by impermissible configuration data) an unreasonable action of the R2600/01 may result which can be dangerous to the system.
