Available commands and command descriptions for Master-Slave programming
The Master-Slave application requires the “Master” controller that guides all attached slaves to the Network ”Slaves” that carry out the commands. The “Master” controller can be a Programmable DPS, open frame model - OP-DPS, PC or other controllers that are capable of sending commands to “Slaves”. The “Slave” can be any Magtorx Programmable DPS or Addressable Relays Driver. Every “Slave” must have a unique assigned address in order to communicate with the “Master” controller. Magtorx Programmable DPS, used as a master, is capable of storing an application program up to 24kB in multiple steps - see S-Program for a detailed description of “step”. This section shows the connection diagrams and lists all available commands for Master-Slave programming:

#A[CR] – Address. Writes unique address, in hexadecimal format, for each DPS that is used in the same Network. The hexadecimal value “A” that can be assigned to the Slave DPS is between “1” and “F”. The Master DPS address must always be “0”. Each assigned address must be immediately saved by the Save command $[CR]. Example: assigning and saving address 3 => #3[CR]$[CR]
JA[CR] – ON-Table Mode. The command turns ON the Table Mode of the DPS with address ”A” – also see the Address command. Example: turn ON address 3 => J3[CR]
jA[CR] – OFF-Table Mode. The command turns OFF the Table Mode of the DPS with address ”A”. – also see the Address command. Example: turn OFF address 3 => J3[CR].
LAXXXX[CR] – Control Signal. Writes hexadecimal value “XXXX” to the control register of the device with address “A”. The value can be between “0” and “0FFF”. The command controls current applied to the load connected to the Load Terminal.
PAXXXX[CR] – Soft Start (>> [!] or [?]). Writes the Time Rate in hexadecimal value “XXXX” to the soft start register. The values ranges from ‘‘0”’ to “EA60”. The number EA60 used with this command will produce a Time Rate equal to 12 [s/V], or simply, it will require 60 seconds to reach a full Control Signal of 5 Volts from its 0 Volt value. For a detailed explanation see Soft Start - Soft Stop command description.
QAXXXX[CR] – Soft Stop (>> [!] or [?]). Writes the Time Rate in hexadecimal value “XXXX” to the soft stop register. The values ranges from ‘‘0”’ to “EA60”. The number EA60 used with this command will produce Time Rate equal to 12 [s/V], or simply, it will require 60 seconds to reach the Control Signal value of 0 Volt from the maximum of 5 Volts. For a detailed explanation see Soft Start - Soft Stop command description.
RA[CR] – Addressable Relay (>> [!] or [?]). Turns ON or OFF the relay switches of ARE-4 device with address “A”. Each Addressable Relays Driver has four designated relay drives (RL1, RL2, RL3, & RL4).
The command is specifically created for Magtorx Addressable Relays Driver, model ARE–4. The ARE-4 device requires a unique Address and is treated by the Master Controller as a Slave device.
Table III denotes the command structure capable of activating the relay operation:

The following is the structure description of the Addressable Relay command - RAX[CR]:
where:
“R” – denotes the command
“A” – denotes the Address of the Addressable Relays Driver
“X” – denotes the bit number in hexadecimal form.
* - Don't confuse letters “A” – Address – the second character in the command structure, with the hexadecimal bit number “A” which is the third character in the command structure RAA[CR] – see table above.
The following are schematics for a Master-Slave connection with the use of an Addressable Relays Driver.
Example: turn ON all relay switches of ARE-4 with address 1 => R1F[CR]
Figure 9. A programmable DPS in control of an Addressable Relays Driver ARD-4 connected to controllers that direct the operation of loads L1, L2, L3, & L4. Load L0 is controlled directly by the Master DPS.
Figure 10. A programmable DPS in control of an Addressable Relays Driver ARD-4 connected to external (more powerful) relays and non-Magtorx controllers (power drives) in command (ON-OFF) of loads L1, L2, L3, & L4. Load L0 is controlled directly by the Master DPS.
Note: For more application diagrams see Application for Programmable DPS.
XFFFF[CR] – ON-Slave Mode. This is a global command used to initiate (turn ON) communication with all DPS Slaves. Executing this command will allow the Master to control all DPS Slaves.
X*0000[CR] – OFF-Slave Mode. This is a global command used to terminate (turn OFF) communication with all DPS Slaves.
ZABCD[CR] – S-Program. Stores (saves) the program, in hexadecimal format into the DPS memory. For a detailed explanation see the following description.
$[CR] - Save. Saves the ”#A[CR]” command assigned to the DPS into the memory during the programming process.
