3.5.3.2 Priority 2 - Comms Errors

Snnn D/Cnn ERRnn

This indicates an error in the communications link between the CNC and a door controller. In this

case ERRnn represents the error number, e.g. S001 D/C03 ERR01. Error numbers currently

displayed are 01, 02, 03, 17 and 18. If there is more than one error at any one time, the

display will show each in turn, allowing 3 seconds for each message.

PAC Portico equipment may report the following communications errors, which are given to assist

in diagnosis of any problems that may occur on the system, either during commissioning or normal

system operation:

Comms Error 1 means a door controller was polled but no reply was received. This may be due to:

• The door controller may be disconnected from the communications cable.

• The door controller may be switched off.

• The door controller may be faulty.

• One or more door controllers may have the same address set.

Note

A Comms Error 1 can only occur on a six wire bus link.

Comms Error 2 means that an incorrect reply was received to an issued command. This type of error

rarely occurs and is usually due to an incorrect system type on the master, noise on the cable or a

software incompatibility.

Comms Error 3 means the reply from a door controller to a command was not received or understood.

This may be due to:

• Faulty communications cabling.

• One or more door controllers may have the same address set.

Comms Error 17 means that there is a problem with the dial-up device at either the CNC or the remote

site. This type of error is sent to the administration software as one of the following transactions:

• Modem not connected.

• Re-dialing.

• Line unobtainable.

Comms Error 18 means that although communications was established with the remote dial-up device,

the CNC was unable to communicate with the door controller at the remote site. This type of error is

reported to the administration software as D/C Not Responding.

3.5.3.3 Priority 2 - Updates/On-line

SITE nnn=nnnnn

SITE nnn*nnnnn

This display indicates that the CNC is storing updates waiting to be sent to a site or the CNC is on-line

with a particular site. Updates are changes to the administration system database that need to be

transmitted to door controllers on the sites. A large number of updates are created when a download is

initiated. Updates are also queued up when changes are made at the administration system for a dial-

up site that is not currently on-line.

A maximum of 8 sites will be reported on this display. The number of updates for a particular site will be

displayed for 3 seconds.

If more than 8 sites have updates waiting, the following rules will apply:

The number of updates for any sites that are currently on-line will always be displayed, regardless of the

number of updates outstanding.

The remaining ‘gaps’ in the display buffer will be filled by the sites that have the largest number of queued

updates.

For example, if 3 sites are currently on-line and a total of 12 sites have updates waiting, the number of

updates for the 3 sites that are on-line and for the 5 off-line sites with the highest number of updates

queued will be displayed.
