Configuration

These settings are normally handled during commissioning or service.

Use this page to enable vNet and to enable only the fixed module positions that are physically installed in the system.

Confirm that the selected equipment supports vNet on the RS485 side used for expansion modules.
Identify which ADAM modules are physically installed in the panel or installation.
Match each installed module to its fixed vNet position before parameters are entered.

Enable vNet

Use VNMON to enable or disable the shared vNet runtime.

Parameter Index Range Format Default Example

VNMON

0..1

0 = vNet disabled

1 = vNet enabled

VNMON 1

When vNet is disabled, no vNet expansion modules are used by the system.

Enable installed module positions

Each VNMODUL## parameter represents one fixed vNet position.

Set the parameter only when a supported ADAM module is physically installed in that position. Leave unused positions disabled.

The position and its vNet node address are fixed by the vNet layout. During setup, the user enables the correct predefined position rather than selecting a free node number.

Parameter Index Range Format Default Example

VNMODUL##

Fixed position ids

0, 2, 8, 32, 128

0 = Position not used

A supported non-zero value enables the ADAM module assigned to that fixed position

VNMODUL30 2

Only the ADAM values used in the standard vNet setup are listed here.

Parameter	Disabled	Enabled value	Enabled result
VNMODUL10	0 = Position not used	2	Enables analog input position 1, node 11, ADAM 4017
VNMODUL12	0 = Position not used	8	Enables analog input position 2, node 13, ADAM 4017
VNMODUL14	0 = Position not used	32	Enables analog input position 3, node 15, ADAM 4017
VNMODUL16	0 = Position not used	128	Enables analog input position 4, node 17, ADAM 4017
VNMODUL20	0 = Position not used	2	Enables analog output position 1, node 21, ADAM 4024
VNMODUL22	0 = Position not used	8	Enables analog output position 2, node 23, ADAM 4024
VNMODUL24	0 = Position not used	32	Enables analog output position 3, node 25, ADAM 4024
VNMODUL26	0 = Position not used	128	Enables analog output position 4, node 27, ADAM 4024
VNMODUL30	0 = Position not used	2	Enables digital input position 1, node 31, ADAM 4051
VNMODUL32	0 = Position not used	8	Enables digital input position 2, node 33, ADAM 4051
VNMODUL34	0 = Position not used	32	Enables digital input position 3, node 35, ADAM 4051
VNMODUL40	0 = Position not used	2	Enables digital output position 1, node 41, ADAM 4056
VNMODUL42	0 = Position not used	8	Enables digital output position 2, node 43, ADAM 4056
VNMODUL44	0 = Position not used	32	Enables digital output position 3, node 45, ADAM 4056
VNMODUL50	0 = Position not used	2	Enables combined digital I/O position 1, node 51, ADAM 4055
VNMODUL52	0 = Position not used	8	Enables combined digital I/O position 2, node 53, ADAM 4055
VNMODUL60	0 = Position not used	2	Enables relay output position 1, node 61, ADAM 4069
VNMODUL62	0 = Position not used	8	Enables relay output position 2, node 63, ADAM 4069

Typical examples

VNMON 1 enables vNet
VNMODUL30 2 enables digital input position 1 and adds the first ADAM 4051 digital input module when vNet is active
VNMODUL40 2 enables digital output position 1 and adds the first ADAM 4056 digital output module when vNet is active
VNMODUL50 2 enables combined digital I/O position 1 and adds the first ADAM 4055 module when vNet is active
VNMODUL60 2 enables relay output position 1 and adds the first ADAM 4069 relay output module when vNet is active

Practical notes

Only the enabled positions add channels to the system.
Unused positions do not reserve channel numbers.
The first added channel number depends on how many built-in channels of the same type the equipment already has.
Channel numbering is explained on I/O mapping.
Correct RS485 wiring and termination are important for stable operation.
