Be observant that forcing of binary inputs and outputs on an IED, with inappropriate
setup, can result in potential danger.
10.8.2 How to enable forcing
GUID-50280F59-A98C-4E48-AB6D-2B4C138943DD v2
To enable forcing, the IED must first be put into IED test mode. While the IED is not in test mode, the
LHMI/PCM600 menus that relate to forcing will not have any effect on the input/output status due to
safety reasons.
10.8.2.1 Enable forcing by using LHMI
GUID-41F7C636-75BC-42EF-A955-4BD9E347619E v2
1. Enable IED TESTMODE by setting IEDTestMode to On under Main menu /Test /IED test mode /
TESTMODE:1 .
IEC15000029 V1 EN-US
2. Exit back to the root menu.
3. Select Yes in the save dialogue box.
Once the IED is in test mode the yellow Start LED starts to blink.
10.8.2.2 Enable forcing using TESTMODE function block
GUID-DD17B7D6-516F-4561-9D30-906B968EAFE0 v2
• Use the TESTMODE function block, appropriately configured in PCM600/ACT.
It may be convenient to control the input on mentioned component from, for example, an LHMI function
key or similar during commissioning to quickly and easily enter IED test mode.
10.8.3 How to change binary input/output signals using forcing
GUID-7DF9FAF1-68B1-49AF-9DE4-2A8D6F6FAEFE v2
Once the IED is in IED test mode, the LHMI/PCM600 menus can be used to control input/output signals
freely.
