In industrial automation, the five IEC 61131-3 languages are pivotal tools for control system programming. Among these, Sequential Function Chart (SFC) language, often called GRAPH in the Siemens environment, plays a significant role. SFC provides a graphical representation of sequential control logic, breaking it down into Steps (actions) and Transitions (conditions). These visual elements offer a powerful way to design and implement sequential control logic for industrial automation tasks.
The GRAPH language is how the SFC language (Sequential Function Chart, a.k.a Grafcet) is named in the Siemens environment. The SFC language is a graphical language where you build sequences as successions of Actions/Conditions known as Steps (actions) and Transitions (conditions). Its main purpose is to serve as a graphical representation for designing and implementing sequential control logic in industrial automation applications. In GRAPH programming, control logic is structured as a series of interconnected charts (sequences), with each chart containing graphical elements (steps and transitions). Steps represent specific actions or operations, while transitions define the conditions that lead from one step to another.
In industrial automation, the GRAPH (SFC) language stands as an indispensable tool for engineers and automation professionals. Its primary purpose is to provide a graphical means of representing and implementing sequential control logic. This language allows for the creation of logical sequences, with Steps embodying actions and Transitions embodying conditions that dictate the flow of control. The ability to design and execute such control logic is pivotal in a wide range of industrial applications, from manufacturing processes to complex machinery control. The GRAPH language's visual nature enhances the comprehensibility of automation workflows, facilitating efficient troubleshooting, maintenance, and modification of control sequences, and ultimately contributing to the advancement of industrial automation systems.
Siemens Advanta and Microsoft collaborated to address your core challenges and develop City Graph - an Open Urban Platform, which supports digital models of urban design, providing rich context to enable the new generation of city applications. It is built on Siemens MindSphere cloud-based open IoT platform, that connects all kinds of devices and models the relationship between spaces, devices, and people in a graph. It utilizes Microsoft services including Azure Digital Twins, Azure IoT Hub, Azure Active Directory, ML and advanced analytics. The platform offers cities the possibility to break through information silos and, for the first time, have access to information where it can be placed into proper context.
To get a fair digital representation of a city we need to create a model of the reality and have the possibility to add context to the entities, e.g. relationships between city operational systems and data bases. Therefore, different domains (electricity, individual and public transportation, waste disposal, etc.) can be merged in one digital city model. Having a graph with entities of the real world and enriching them with live data coming from connected devices and integrated legacy systems and their relationships is the key enabler to control the present, track the past and predict the future.
You can divide the graphics window into multiple viewports, each displaying a different view, such as the model view, animation, animation of specific components, or XY graphing. For this activity, you will divide the graphics window into two viewports.
Amatrol's PLC graph programming curriculum teaches a variety of PLC graph programming topics, including: S7 graph programming language; project creation; actions and conditions; sequence branches; interlocks and supervisions; and diagnostic messages. Within these topics, learners will study objectives like creating an S7 graph project; adding conditions to an S7 graph project; adding an interlock to a step; and configuring and viewing S7 graph diagnostic messages.

Multiple hypermetabolic metastases in the liver, mediastinal lymph nodes, vertebrae, and soft tissue sharply delineated in 18F FDG[a] PET/CT study on Biograph Vision reconstructed with high resolution at 440 x 440 matrix.
A 67-year-old male with progressive muscular stiffness, difficulty in swallowing, and autonomic dysfunctions with no response to levodopa therapy; undergoing evaluation for striatal multi-system atrophy. A Fludeoxyglucose F 18 Injection.[a] (18F FDG) PET/CT scan of the brain was performed on Biograph Vision. The study shows normal uptake in brain with excellent delineation of functioning cortex and sharp contrast between cortex and white matter. Additionally there is sharp basal ganglial edge definition, especially the sharp margins and distinct separation of the head of caudate nucleus and putamen.
A 73-year-old male with prostate cancer treated with brachytherapy presented with biochemical relapse. The patient underwent PET/CT study following injection of androgen receptor imaging agent Fluoro-dihydrotestosterone (18F-FDHT) in order to assess presence of androgen receptor positive recurrence. PET/CT was performed on Biograph Vision. Images showed tracer within cardiac and vascular blood pool as well as in the liver. Significant clearance of tracer through the biliary tract and gall bladder, kidneys, and intestines is visualized. No well defined focal uptake suggestive of androgen receptor-avid metastatic lesions is visualized, although primary prostate bed showed significant uptake on higher intensity images. Sharp delineation of vascular structures, especially cavernous and sigmoid sinuses as well as carotid and subclavian vessels reflect the high overall image quality and low noise level in the Biograph Vision images.
A 78-year-old male with primary prostate cancer underwent 68Ga-PSMA PET/CT initial staging. PET/CT was performed on Biograph Vision. The images showed high tracer uptake in kidneys, salivary glands, and bladder, which are at physiologically normal levels. The liver, spleen, and intestines also show lower but normal levels of uptake as well. There is also focal hypermetabolism in the prostate reflecting primary tumor and the small hypermetabolic right external iliac lymph node is suggestive of solitary nodal metastases. No other PSMA-avid metastatic lesions are visualized. Sharply delineated renal, salivary gland, bladder, and intestinal margins reflect the high overall image quality and low background noise level in the Biograph Vision images.
A 49-year-old woman with a history of operated ovarian carcinoma with suspected recurrence underwent 18F FDG PET/CT for restaging. A PET/CT was performed on Biograph Vision. The images showed hypermetabolic metastases in the right obturator node, anterior pelvic wall above, and adjacent to the bladder as well as multiple small liver metastases in the posterior aspect of the right lobe (Segment VII) and in the caudate lobe. Sharp delineation of small liver lesions with high contrast compared to normal liver without respiratory gating reflect the overall high image quality and high lesion contrast to background in the Biograph Vision images.
A 69-year-old male with a history of operated colorectal carcinoma with suspected recurrence underwent 18F FDG PET/CT for restaging. A PET/CT was performed on Biograph Vision. The images showed sharp delineation of small hypermetabolic metastasis in the right lobe of liver near the dome of diaphragm (Segment VII). Intense uptake in the abdominal wall is suggestive of metastatic deposit. Mildly increased uptake in mediastinal lymph nodes are possibly secondary to inflammation. High contrast of small liver metastases without significant motion related blurring even without respiratory gating reflects high overall image quality and increased lesion contrast to background in the Biograph Vision images.
A 77-year-old female with a history of breast carcinoma treated with left mastectomy and chemo-radiotherapy presented with pain in the thoracic wall along with pleural effusion. The patient underwent 18F Fluoroestradiol (FES) PET/CT to assess presence of estrogen receptor (ER) positive metastases. A PET/CT was performed on Biograph Vision. High resolution PET images show faint uptake in the left pleura suggestive of ER positive pleural thickening. The PET/CT images also sharply delineates physiological uptake in the gall bladder and biliary tract and intestine reflecting hepatobiliary clearance of tracer. Sharp definition of biliary tree with high contrast compared to background even at 440 x 440 matrix reconstructed resolution reflect the high overall image quality of Biograph Vision images.
