Physical Layer (PHL) for UCR

Communications Connector

- UCR Control Unit for Robot can be

connected to a PLC using a five-pin

Communications Cable (Ref. 0020261).

- Serial communication type is RS-232,

configured as 19200 bps, eight (8) data

bits, no (N) parity bit and one (1) stop bit

(19200-8N1).

- The communication connector provides

“switch” input.

- For a proper connection, it is necessary to

connect only 3 cables to the corresponding

3 pins at a typical DB9 male connector (PLC

or computer).

Communication Protocol

Communication protocol was developed to help you set up the communication between soldering

stations and a robot (PC or PLC).

It can be applied to the following JBC’s control units:

- UCR Control Unit for Robot

- ALE Automatic-Feed Soldering Control Unit

- NAE 2-Tool Control Unit

- DDE 2-Tool Control Unit

- DME 4-Tool Control Unit

- HDE Heavy Duty Control Unit

The protocol is divided into three layers:

- PHL: Physical layer

- DLL: Data link layer

- APL: Application layer (depends on station model)

Physical Layer (PHL) for ALE, NAE, DDE, DME and HDE Control

Units

- JBC control units can be connected to a PLC by a RJ12 direct cable (ref. 0019751) and DB9-

RJ12 Adapter (ref. 0015383).

- Serial communication type is RS-232, configured as 19200 bps, eight (8) data bits, no (N) parity

bit and one (1) stop bit (19200-8N1).

Communications Connector

Switch input activates the Control Box, using a relay or transistor digital output. Digital output from

the PLC to the switch input can be PNP or NPN style, as well as a relay contact.

Start of transmission.

Corresponds to the character STX of ASCII code (0x02).

The Source Address range is from “00” to “99”.

The factory setting for Robot Address is “00”.

The Target Address range is from “00” to “99”.

Factory settings for JBC devices are as follows:

· Soldering Stations Address is “01”

· Solder Feeder Address is “10”

· Fume Extractor Address is “20”

Four Codes are used (see table from page 5).

Select the command to be used (see pages 11-29).

Composed of ﬁve digits. First tens of thousand is sent and thereafter

successively until the last unit.

Example: in order to send “12345” it is ﬁrst sent “1”, and ﬁnally “5”.

If it is a negative number, the minus sign is at the tens of thousands

digit, shown as an ASCII character “-”.

Example: In order to send “-50”, the data will be sent is “-0050”.

If the number has less than ﬁve digits, then zeros will be placed before.

Example: in order to send “375” the data will be sent is “00375”.

End of transmission.

Corresponds to the ASCII code character ETX (0x03).

This is an error Check Field. The value is obtained by calculating the

logic function XOR for the whole frame, excluding the BCC.

Command

Frame A

Frame Reception

The Robot sends a Command Frame to the JBC device. This information is send to the Application

Layer (APL). The Command Frame obtained from the robot is correct if it has the correct length and

“starts with STX + finishes with ETX + correct BCC”.

The JBC device will send a Response Frame. In the case of a Response Frame with errors, the Robot

determines the number of consecutive Command Frames that will send to the JBC device. If the

Robot receives a Response Frame with errors, it cannot be resent by the JBC device.

The JBC device does not expect ACK/NAK from the Robot.
