Description
UNIOP MKDG-06-0045 Operator Interface
Product Overview
The UNIOP MKDG-06-0045 is a legacy UniOP operator interface designed for PLC, PC/printer, and auxiliary control-system applications. The original Exor technical documentation identifies this exact -0045 variant as a graphic LCD display with 260 × 64 pixels, supporting 8 lines of 40 characters and providing 23 function keys with an alphanumeric keypad. This is a conventional keyed operator panel rather than a modern touchscreen HMI, making it particularly relevant to older machine-control and industrial automation installations where the existing application was designed around physical keys.
Physically, the UNIOP MKDG-06-0045 has a 220 × 176 mm front panel and a specified panel cutout of 207 × 163 mm. The original technical note gives the -0045 version a 76 mm cutout depth, while the related -0050 version uses a different Snap-top mechanical arrangement and 79.7 mm depth. That distinction is important during retrofit work; the two suffixes should not be treated as interchangeable simply because they belong to the same MKDG-06 family.
The electrical and mechanical information available for the -0045 identifies it as a 24 VDC, 0.4 A operator interface. Current legacy-component references classify it as an HMI/MMI/operator-interface product and indicate that the manufacturer has discontinued it. Some current replacement references point toward the EX707 or eSMART07M families, but those should be treated as replacement candidates requiring application and cutout review rather than automatic drop-in equivalents.
Product Introduction
When a machine still depends on a keyed operator panel, replacing the HMI is not simply a matter of matching display size. The MKDG-06-0045 combines a specific 260 × 64 graphic display, 23-key interface, PLC/PC auxiliary connectivity, and a defined panel cutout.
For a legacy HMI replacement, preserving the mechanical opening and determining how the original UniOP application communicates with the controller should come before selecting a newer panel. A modern touchscreen may be electrically capable yet still require application conversion, new cabling, and a different mounting arrangement.

Major Features / Practical Advantages
Graphic LCD designed for keyed operation
The 260 × 64-pixel graphic LCD was designed around a text-oriented operator interface rather than a modern graphical touchscreen. With eight lines of 40 characters, it can present substantial machine status and parameter information without requiring a touch display.
For an existing machine, this can actually be an advantage. Operators who are accustomed to physical keys do not have to relearn basic navigation simply because the replacement strategy has not yet been modernized.
MKDG-06-0045
23 function keys and alphanumeric keypad
The 23 function keys provide dedicated physical controls for the UniOP application. The integrated alphanumeric keypad also allows parameter entry without an external keyboard.
This makes the MKDG-06-0045 fundamentally different from a generic LCD monitor. Its value lies in the combination of display, keys, controller communications, and the UniOP runtime environment.
Compact panel footprint
The specified 220 × 176 mm front dimensions and 207 × 163 mm cutout make physical verification straightforward. Before ordering a replacement, measure the existing enclosure opening rather than assuming that another MKDG-06 family unit will use the same dimensions.
The 76 mm cutout depth for the -0045 variant is also worth checking where the panel is installed in a shallow cabinet or machine enclosure.
PLC and PC/auxiliary connectivity
The original ordering information identifies PLC, PC/Printer, and auxiliary ports. That indicates the panel was designed as an operator-interface terminal within a broader control-system environment rather than as a standalone display.
The exact controller protocol and cable arrangement should still be confirmed from the machine’s original application documentation. The model number alone is not sufficient evidence for assuming a particular PLC communication protocol.
24 VDC industrial power
The unit is identified as a 24 VDC, 0.4 A operator interface. That makes the supply arrangement familiar in industrial control cabinets, but the replacement power requirement should still be checked against the machine’s existing 24 VDC distribution and protection.
Legacy replacement relevance
Current component references i the as discontinued and list EX707 or eSMART07M as suggested replacement candidates. Those references themselves caution that specifications should be reviewed before treating the alternatives as replacements.
That is the correct engineering approach. A replacement HMI has to match more than the voltage: application software, communications, mounting dimensions, cable interfaces, key functions, and operator workflow all matter.

FAQ
Can I the directly with an EX707?
Not without checking the application. EX707 is listed as a suggested replacement, but that does not establish mechanical, software, protocol, or cable-level equivalence. Confirm the original UniOP application, PLC interface, panel opening, and operator-key requirements first.
What is the display resolution?
The original Exor technical note specifies a 260 × 64 pixel graphic LCD with an eight-line, 40-character text capacity.
What is the panel cutout size?
The specified cutout is 207 × 163 mm, with a front dimension of 220 × 176 mm. The -0045 version has a documented cutout depth of 76 mm.
the a touchscreen?
No. The original documentation describes a graphic LCD with 23 function keys and an alphanumeric keypad. It is a keyed operator interface rather than a touchscreen HMI.
Can I hot-swap this HMI?
Do not ass The is an operator terminal rather than a typical hot-swappable PLC I/O module. Replacement normally involves disconnecting power and communication wiring and should be performed according to the machine’s maintenance procedure.
Does it support firmware v3.1?
The model number does not establish a firmware version. The correct compatibility check is the installed UniOP application/runtime version, controller protocol, communication hardware, and replacement terminal capabilities.
What PLC protoco the support?
The original technical note identifies PLC, PC/Printer, and auxiliary ports, but the available documentation reviewed here does not establish a single universal PLC protocol for every installation. The actual machine application and UniOP configuration should therefore be checked before specifying a replacement.
the still manufactured?
Current legacy-component references identify it as discontinued by the manufacturer. This makes the exact hardware marking and condition particularly important when sourcing a replacement.
Is the -0050 interchangeable with the -0045?
Not automatically. The original Exor documentation gives the -0045 a 76 mm cutout depth and the -0050 a 79.7 mm depth with Snap-top construction. The mechanical installation therefore differs even though both belong to the family.
Procurement Note
For a replacement, the most important checks are the complete model suffix, panel cutout, depth clearance, PLC communication arrangement, existing UniOP application, keypad requirements, and 24 VDC power distribution.
The mechanical dimensions are unusually important with this component. Confirm the 207 × 163 mm cutout and 76 mm depth before accepting a proposed replacement. A modern HMI can be technically more capable and still create a cabinet modification project if its mounting dimensions or rear clearance differ.
For legacy inventory, distinguish carefully between new surplus, never-used stock, and refurbished units. Request photographs of the actual front label and rear connector area. the is discontinued, preservation of the existing application and communication configuration may be more difficult than sourcing the physical panel itself.
A replacement reference such as or eSMART07M should therefore be presented as a migration candidate, not as a guaranteed drop-in replacement, until the PLC protocol, UniOP project, mounting dimensions, and operator-interface requirements have been checked.
