INFORMATION

Finding PLCStop quickly

If you just want to change the PLCStop setting, but not any of the segments in your scenario, it is

quickest to use [←] once after entering the scenario, since this submenu is wrap-around, just like

all other.

4.5.6 Submenu “Service-Option”

This menu has two sections. In “Service Code” you can enter a service code (see Tab. 17).

“Baud Rate” is used to change the baud rate. There are five possible values: 9600, 19200, 38400,

57600 and 115200 (new MDCs are set to 115200).

Service Code Explanation

If you enter 33, you can activate or change the adjust offset (see

paragraph 7.12 "Adjust Offset", page 75).

If you enter 35, the adjust offset is set back to “0”.

1000

If you enter 1000, you enter a further submenu containing the options listed

in the table below (see Tab. 18).

Option Explanation

SingleDosOK

You can select between the possibilities that the SingleDosOK signal is

switched per pulse or per setup. (Default setting is per pulse. For the pin

configuration of the PLC interface, see Page 113.)

DosOK with Delay

You can select, if before switching the signal DosOK there should be one

delay executed at the end. (Default setting is OFF.)

Auxiliary Mode

Here the auxiliary mode can be switched ON or OFF (see paragraph 7.11

"Auxiliary Mode", page 74).

Factory Settings

Here any parameters can be returned to the default factory settings (see

paragraph 7.10 "Factory Settings", page 73). You have got four alternatives:

• Setup 0 – 3 (the parameters of the working configuration and the setups

1 to 3 are returned to the factory settings)

• Reset ALL (all parameters are returned, including the settings of the

scenarios; also the heater will be turned OFF and the temperature set to

10°C, cooling will be turned OFF, set to 80 °C and the cooler offset will be

set as 0 %)

• Scenario (the parameters and settings of the scenarios are returned to the

factory settings)

• Setup ALL (the parameters of the working configuration and all setups

are returned, setups 4 – 10 receive values of setup 0)

4.6 Memories of the MDC

The MDC contains several memories to save parameter setups.

The first one is the RAM (Random Access Memory). Here the parameters of the current dispense

process will be saved. This memory will be erased when the controller is switched of or

disconnected from power. When starting again, the MDC will load the first of eleven parameter

memory sets saved on the EEPROM (Electrically Erasable Programmable Read Only Memory) into

the RAM. This first parameter setup is also called the “EEPROM current working parameter

configuration”, or short “working configuration” or “EEPROM working configuration”.

The parameter set in the EEPROM working configuration is usually the same as the parameter set

saved in the RAM memory. When using the keypad to program the controller, the two memories

will always have the same contents. The only way to create a difference in the parameter set

saved in the RAM and in the EEPROM working configuration is by using some special commands

through the RS-232C.

The remaining ten EEPROM memory sets can be used to save different parameter setups when

programming the controller through the keypad interface (use the command [save]).

In order to change the values saved in the EEPROM working configuration you may use the MDC

keypad (enter the parameters in the menu “Pulse Parameters”, then press [enter]).

Or you may use one of the following commands via RS-232C:

• TRIGGER:ASET:<Rising>,<Open Time>,<Falling>,<Needle Lift>,<Number of Pulses>,<Delay>,1

• STRIGGER:ASET:<Rising>,<Open Time>,<Falling>,<Needle Lift>,<Number of Pulses>,<Delay>,1

All values transmitted to the control unit by one of the following commands will not be saved in

the EEPROM working configuration.

• TRIGGER:ASET:<Rising>,<Open Time>,<Falling>,<Needle Lift>,<Number of Pulses>,<Delay>

• STRIGGER:ASET:<Rising>,<Open Time>,<Falling>,<Needle Lift>,<Number of Pulses>,<Delay>

Instead it will remain in the RAM memory until erased by another RS-232C command, or when

the control unit is switched OFF and the EEPROM is read out into the RAM during restart. The

reason for having these two different types of commands (the distinction is the “1” at the end) is

that it takes up to 1 sec to save the parameter set in the EEPROM.

On top of the working configuration and the ten parameter setups there is another parameter

set-ting saved in the software on the EEPROM. This is called the “factory setting”. It cannot be

changed by the user. It may be loaded to the working configuration and the RAM memory after

major disturbances of the system.

Additionally there is the possibility to save combinations of setups, so called “Scenarios” (see

paragraph 7.9 "Scenarios", page 70).
