AADvance Workbench, AAdvance-Trusted SIS Workstation, ISaGRAF, Trusted Toolset, and FlexiSafe Reset Coil Order of Execution Posted on August 2, 2020 by Brandy McNeil AADvance Workbench, AAdvance-Trusted SIS Workstation, ISaGRAF, Trusted Toolset, and FlexiSafe Reset Coil Order of Execution Product Safety Group 1201 South Second Street Milwaukee, WI USA 53204 firstname.lastname@example.org expanding human possibility™ PRODUCT SAFETY ADVISORY Notice of Potential Unsafe Condition Rockwell Automation issues a Product Safety Advisory when it identifies a product(s) anomaly that may potentially cause harm to personnel, capital equipment loss or environmental damage. Immediate action is required as identified below. AADvance Workbench, AAdvance-Trusted SIS Workstation, ISaGRAF, Trusted Toolset, and FlexiSafe Reset Coil Order of Execution Reference: 2020-08-002 Date: August 2020 This Product Safety Advisory informs you of an anomaly that exists with the AADvance® Workbench, AADvance-Trusted SIS Workstation (SISW), ISaGRAF®, Trusted® Toolset, and FlexiSafe™ applications. When using ladder logic programming, if a reset coil (Reset) is applied to the variable enabling a branch operation, subsequent branch operations of the same rung will not execute. – Product Identification – The affected products are: • AADvance Workbench versions 1.x and 2.x, catalog numbers T908x • SISW version 1.0 (for Trusted products), catalog numbers T8090 and T8090M • ISaGRAF all versions up to, but not including, V6.06.08 • Trusted Toolset all versions, catalog number T8082U and T8082D • FlexiSafe all versions PRODUCT SAFETY ADVISORY Page 2 of 5 expanding human possibility™ – Description – An anomaly exists with the AADvance Workbench, AADvance-Trusted SIS Workstation (SISW), ISaGRAF, Trusted Toolset, and FlexiSafe applications. When using ladder logic programming (not ladder elements in the FB Editor), if a reset coil (Reset) is used in a branch operation where one of the activating coil contacts is the same as the coil being reset, subsequent elements in that branch or subsequent branches of the same rung will not execute. The example at the left shows two possible conditions affected by this anomaly. In the first example rung, the Reset coil is place first in the branch. Operations placed after the Reset coil will not execute, as shown identified by the red X. In the second example rung, the Reset coil is placed in the middle of the branch. Operations placed before the Reset coil will execute, as shown by the green checkmark. However, operations placed after the branch will not execute, as shown by the red X. Further, the example at the left shows a configuration where the use of the Reset coil with multiple branches results in rung operations in subsequent branches not executing. When using ladder logic programming (not ladder elements in the FB Editor), if a contact is used to activate many branches within the same rung AND the state of this contact is changed before the last branch of the rung, then subsequent branches of the same rung will not execute. – Temporary Workarounds – Customers are advised to review all ladder logic where Reset coils are used and verify the Reset coil operation is place last in the branch operations.
