SERVCFG is the driver configuration applet for the INGEAR Allen-Bradley PLC ActiveX control. It provides the unique capability to apply hardware and communication characteristics that are independent of the ActiveX. This feature allows you to change communication settings and PLC type with negligible changes to your application. In many cases, you can change driver and PLC type, without the need to change or recompile your application. For example, you write and test your application using serial communications to a PLC-5, and deploy to a SLC 5/05 simply by changing the SERVCFG settings.
Button Operations
Apply – Applies the hardware and communication characteristics to the currently selected Adapter. You must click Apply for each Adapter you configure.
Done – Saves any setting changes you made, then closes the SERVCFG program. Any changes you made will be used the next time you start your application that uses the INGEAR Allen-Bradley PLC ActiveX.
Hardware Settings
Hardware Settings tells the INGEAR driver about physical communication interface you’ll be using to communicate to your Allen-Bradley PLC network.
Adapter – The Adapter setting allows your application to use more than one hardware device at a time. You can configure up to a maximum of 8 Adapters. Each Adapter will run in its own driver thread for optimum performance.
Enabled – The Enabled setting applies to physical devices such as COM Ports and Bus Cards (e.g. 1784-PKTX) only. When Enabled is checked, the INGEAR driver will initialize the Device, start a driver thread, and make the device available ready for use by the ActiveX control. If Enabled is unchecked, the INGEAR driver will bypass the device start up. When using Ethernet Device Types, the Enabled setting is unchecked.
Device Type – Device Type applies the hardware characteristic to the Adapter. Device Type supported are:
· Serial DF1 (Full-Duplex)
· AB 1784-KT (ISA Bus Card)
· AB 1784-KTX and 1784-PKTX/D (ISA Card)
· AB 1784-PKTX (PCI Card Single Channel Only)
· AB 1784-PCMK (PCMCIA Card WIN 9x/NT Only)
· SST 5136 SD (ISA and PCI Card)
· Ethernet
Comm Port – Selects the COM port used when the Device Type = Serial DF1
Base Address – Is the card memory address for 1784-KT/KTX/PCMK/SST 5136 Bus cards.
I/O Port – Is the I/O port address for SST 5136 Cards
Communication Settings
Communication settings tells the INGEAR driver about the type of Allen-Bradley PLC you are communicating to as Baud Rates and Node ID’s of your communication interface.
PLC Type – This setting specifies the Allen-Bradley Type of PLC you are communicating to. Supported PLC Types are:
· ControlLogix/CompactLogix (ENET)
- Ethernet to ControlLogix
- Ethernet to CompactLogix
· MicroLogix 1100 (ENET)
- Ethernet to MicroLogix 1100.
· SLC/Micro (ENET/DH485/DF1)
- Ethernet to a SLC 5/05
- Serial DF1 SLC 5/02, 5/03, 5/04, 5/05
- Serial DF1 MicroLogix 1000/1100/1200/1500
- DH485 via 1747-UIC (USB to Serial/DH-485)
- DH485 via 1784 PKTX/PCMK/KTX
· SLC/Micro (1761 NET ENI)
- Ethernet / DF1 bridge to SLC 5/02, 5/03, 5/04, 5/05
- Ethernet / DF1 bridge to MicroLogix 1000/1100/1200/1500
· SLC 5/04 (DH +)
- Data Highway Plus to SLC 5/04
· SLC 5/04 (CLX Gateway DH+)
- ControlLogix Gateway via 1756 DH+/RIO to SLC 5/04
· PLC5 (ENET/DH+/DF1)
- Ethernet to PLC-5 (direct or sidecar)
- Data Highway Plus to PLC-5
- Serial DF1 to PLC-5
· PLC5 (1761 NET ENI)
- Ethernet / DF1 bridge to PLC-5
· PLC5 (CLX Gateway DH+)
- ControlLogix Gateway via 1756 DH+/RIO to PLC-5
· PLC5 (CLX Gateway CNET)
- ControlLogix Gateway via 1756-CNB to PLC-5 ControlNet
LinkSpeed – Sets the baud rate of the communication interface.
· Serial DF1 Devices – This setting must match Channel 0 settings of the controller.
Support serial baud rates are 9600 / 19.2k / 38.4k / 57.6k / 115k / 230k
· DH+/DH-485 Devices – This setting must match the baud rate of the network.
Supported DH+ baud rates are 57.6, 115K and 230K
Support DH-485 baud rates are 9600 and 19.2K
Checksum – CRC or BCC. Applies to Serial DF1 Device Types and must match the Channel 0 settings of the controller.
Timeout – Applies to Serial DF1 and bus card Device Types. This setting is the maximum amount of time the INGEAR driver will wait for a response from the controller. If the driver does not get a response within this amount of time, the OnErrorEvent handler of the ActiveX will fire.
Station ID – Applies to bus card Device Types:
· DH+ Cards – This is the DH Plus Node address (00-77 octal) you are assigning to the card. The DH Plus node address must be unique to the network. The INGEAR driver will fail DH+ initialization if the Station ID setting conflicts with another node on the network.
· DH-485 Cards – This is the DH-485 node address (00-31 decimal) you are assigning to the card. The DH-485 node address must be unique to the network. The INGEAR driver will fail DH-485 initialization if the Station ID setting conflicts with another node on the network.
MaxNodes - Applies to DH-485 networks only. This should be the highest node address on the DH-485 network. This setting affects DH-485 token rotation and can lead to better network performance.
TermName (Optional) – This is a user defined 7 character string that can be used to identify your DH+/DH-485 to other nodes on the network.
